CVE-2025-66452 (GCVE-0-2025-66452)

Vulnerability from nvd – Published: 2025-12-11 22:52 – Updated: 2025-12-12 19:28

Title

LibreChat's lack of JSON parsing error handling can lead to XSS

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.8.0 and below, there is no handler for JSON parsing errors; SyntaxError from express.json() includes user input in the error message, which gets reflected in responses. User input (including HTML/JavaScript) can be exposed in error responses, creating an XSS risk if Content-Type isn't strictly enforced. This issue does not have a fix at the time of publication.

Severity ?

5.3 (Medium)

CVE-2025-66451 (GCVE-0-2025-66451)

Vulnerability from nvd – Published: 2025-12-11 22:33 – Updated: 2025-12-12 19:29

Title

LibreChat's Improper Input Validation in Prompt Creation API Enables Unauthorized Permission Changes

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.8.0 and below, when creating prompts, JSON requests are sent to define and modify the prompts via PATCH endpoint for prompt groups (/api/prompts/groups/:groupId). However, the request bodies are not sufficiently validated for proper input, enabling users to modify prompts in a way that was not intended as part of the front end system. The patchPromptGroup function passes req.body directly to updatePromptGroup() without filtering sensitive fields. This issue is fixed in version 0.8.1.

Title

LibreChat JSON Injection in Chat POST Allows Remote Resource Inclusion and PXSS via Image Upload

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.8.0 and below, when a user posts a question, the iconURL parameter of the POST request can be modified by an attacker. The malicious code is then stored in the chat which can then be shared to other users. When sharing chats with a potentially malicious “tracker”, resources loaded can lead to loss of privacy for users who view the chat link that is sent to them. This issue is fixed in version 0.8.1.

Severity ?

8.6 (High)

CVE-2025-66201 (GCVE-0-2025-66201)

Vulnerability from nvd – Published: 2025-11-29 01:26 – Updated: 2025-12-01 14:11

Title

LibreChat is Vulnerable to Server-Side Request Forgery (SSRF) in Actions Capability

Summary

LibreChat is a ChatGPT clone with additional features. Prior to version 0.8.1-rc2, LibreChat is vulnerable to Server-side Request Forgery (SSRF), by passing specially crafted OpenAPI specs to its "Actions" feature and making the LLM use those actions. It could be used by an authenticated user with access to this feature to access URLs only accessible to the LibreChat server (such as cloud metadata services, through which impersonation of the server might be possible). This issue has been patched in version 0.8.1-rc2.

Severity ?

8.6 (High)

CVE-2025-8849 (GCVE-0-2025-8849)

Vulnerability from nvd – Published: 2025-10-30 23:42 – Updated: 2025-10-31 15:09

Title

Denial of Service in danny-avila/librechat

Summary

LibreChat version 0.7.9 is vulnerable to a Denial of Service (DoS) attack due to unbounded parameter values in the `/api/memories` endpoint. The `key` and `value` parameters accept arbitrarily large inputs without proper validation, leading to a null pointer error in the Rust-based backend when excessively large values are submitted. This results in the inability to create new memories, impacting the stability of the service.

Severity ?

5.4 (Medium)

CVE-2025-8850 (GCVE-0-2025-8850)

Vulnerability from nvd – Published: 2025-10-30 19:59 – Updated: 2025-11-05 14:57

Title

Insecure API Design in danny-avila/librechat

Summary

In danny-avila/librechat version 0.7.9, there is an insecure API design issue in the 2-Factor Authentication (2FA) flow. The system allows users to disable 2FA without requiring a valid OTP or backup code, bypassing the intended verification process. This vulnerability occurs because the backend does not properly validate the OTP or backup code when the API endpoint '/api/auth/2fa/disable' is directly accessed. This flaw can be exploited by authenticated users to weaken the security of their own accounts, although it does not lead to full account compromise.

Severity ?

3.1 (Low)

This vulnerability occurs because the backend does not properly validate the OTP or backup code when the API endpoint \u0027/api/auth/2fa/disable\u0027 is directly accessed. This flaw can be exploited by authenticated users to weaken the security of their own accounts, although it does not lead to full account compromise."

CVE-2025-8848 (GCVE-0-2025-8848)

Vulnerability from nvd – Published: 2025-10-22 13:54 – Updated: 2025-10-30 18:22

Title

HTML Injection in Accept-Language Header in danny-avila/librechat

Summary

A vulnerability in danny-avila/librechat version 0.7.9 allows for HTML injection via the Accept-Language header. When a logged-in user sends an HTTP GET request with a crafted Accept-Language header, arbitrary HTML can be injected into the <html lang=""> tag of the response. This can lead to potential security risks such as cross-site scripting (XSS) attacks.

Severity ?

4.8 (Medium)

CVE-2025-7104 (GCVE-0-2025-7104)

Vulnerability from nvd – Published: 2025-09-29 17:10 – Updated: 2025-10-15 16:08

Title

Mass Assignment in danny-avila/librechat

Summary

A mass assignment vulnerability exists in danny-avila/librechat, affecting all versions. This vulnerability allows attackers to manipulate sensitive fields by automatically binding user-provided data to internal object properties or database fields without proper filtering. As a result, any extra fields in the request body are included in agentData and passed to the database layer, allowing overwriting of any field in the schema, such as author, access_level, isCollaborative, and projectIds. Additionally, the Object.Prototype can be polluted due to the use of Object.assign with spread operators.

Severity ?

4.3 (Medium)

CVE-2025-7106 (GCVE-0-2025-7106)

Vulnerability from nvd – Published: 2025-09-23 09:54 – Updated: 2025-09-23 19:29

Title

Authorization Bypass due to Incorrect Access Control in danny-avila/librechat

Summary

danny-avila/librechat is affected by an authorization bypass vulnerability due to improper access control checks. The `checkAccess` function in `api/server/middleware/roles/access.js` uses `permissions.some()` to validate permissions, which incorrectly grants access if only one of multiple required permissions is present. This allows users with the 'USER' role to create agents despite having `CREATE: false` permission, as the check for `['USE', 'CREATE']` passes with just `USE: true`. This vulnerability affects other permission checks as well, such as `PROMPTS`. The issue is present in all versions prior to the fix.

This allows users with the \u0027USER\u0027 role to create agents despite having `CREATE: false` permission, as the check for `[\u0027USE\u0027, \u0027CREATE\u0027]` passes with just `USE: true`.

CVE-2025-6088 (GCVE-0-2025-6088)

Vulnerability from nvd – Published: 2025-09-11 00:43 – Updated: 2025-09-11 14:42

Title

Improper Authorization in danny-avila/librechat

Summary

In version 0.7.8 of danny-avila/librechat, improper authorization controls in the conversation sharing feature allow unauthorized access to other users' conversations if the conversation ID is known. Although UUIDv4 conversation IDs are generated server-side and are difficult to brute force, they can be obtained from less-protected sources such as server-side access logs, browser history, or screenshots. The vulnerability permits a logged-in user to gain read-only access to another user's conversations by exploiting the `/api/share/conversationID` endpoint, which lacks authorization checks. This issue is resolved in version v0.7.9-rc1.

Severity ?

4.2 (Medium)

Vulnerability from nvd – Published: 2025-08-05 04:53 – Updated: 2025-08-05 16:19

Title

LibreChat exposes arbitrary chats through Meilisearch engine

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.0.6 through 0.7.7-rc1, an exposed testing endpoint allows reading arbitrary chats directly from the Meilisearch engine. The endpoint /api/search/test allows for direct access to stored chats in the Meilisearch engine without proper access control. This results in the ability to read chats from arbitrary users. This issue is fixed in version 0.7.7.

Severity ?

Vulnerability from cvelistv5 – Published: 2025-12-11 22:52 – Updated: 2025-12-12 19:28

Title

LibreChat's lack of JSON parsing error handling can lead to XSS

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.8.0 and below, there is no handler for JSON parsing errors; SyntaxError from express.json() includes user input in the error message, which gets reflected in responses. User input (including HTML/JavaScript) can be exposed in error responses, creating an XSS risk if Content-Type isn't strictly enforced. This issue does not have a fix at the time of publication.

Severity ?

CVE-2025-66451 (GCVE-0-2025-66451)

Vulnerability from cvelistv5 – Published: 2025-12-11 22:33 – Updated: 2025-12-12 19:29

Title

LibreChat's Improper Input Validation in Prompt Creation API Enables Unauthorized Permission Changes

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.8.0 and below, when creating prompts, JSON requests are sent to define and modify the prompts via PATCH endpoint for prompt groups (/api/prompts/groups/:groupId). However, the request bodies are not sufficiently validated for proper input, enabling users to modify prompts in a way that was not intended as part of the front end system. The patchPromptGroup function passes req.body directly to updatePromptGroup() without filtering sensitive fields. This issue is fixed in version 0.8.1.

Severity ?

5.3 (Medium)

Title

LibreChat JSON Injection in Chat POST Allows Remote Resource Inclusion and PXSS via Image Upload

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.8.0 and below, when a user posts a question, the iconURL parameter of the POST request can be modified by an attacker. The malicious code is then stored in the chat which can then be shared to other users. When sharing chats with a potentially malicious “tracker”, resources loaded can lead to loss of privacy for users who view the chat link that is sent to them. This issue is fixed in version 0.8.1.

Severity ?

8.6 (High)

CVE-2025-66201 (GCVE-0-2025-66201)

Vulnerability from cvelistv5 – Published: 2025-11-29 01:26 – Updated: 2025-12-01 14:11

Title

LibreChat is Vulnerable to Server-Side Request Forgery (SSRF) in Actions Capability

Summary

LibreChat is a ChatGPT clone with additional features. Prior to version 0.8.1-rc2, LibreChat is vulnerable to Server-side Request Forgery (SSRF), by passing specially crafted OpenAPI specs to its "Actions" feature and making the LLM use those actions. It could be used by an authenticated user with access to this feature to access URLs only accessible to the LibreChat server (such as cloud metadata services, through which impersonation of the server might be possible). This issue has been patched in version 0.8.1-rc2.

Severity ?

8.6 (High)

CVE-2025-8849 (GCVE-0-2025-8849)

Vulnerability from cvelistv5 – Published: 2025-10-30 23:42 – Updated: 2025-10-31 15:09

Title

Denial of Service in danny-avila/librechat

Summary

LibreChat version 0.7.9 is vulnerable to a Denial of Service (DoS) attack due to unbounded parameter values in the `/api/memories` endpoint. The `key` and `value` parameters accept arbitrarily large inputs without proper validation, leading to a null pointer error in the Rust-based backend when excessively large values are submitted. This results in the inability to create new memories, impacting the stability of the service.

Severity ?

5.4 (Medium)

CVE-2025-8850 (GCVE-0-2025-8850)

Vulnerability from cvelistv5 – Published: 2025-10-30 19:59 – Updated: 2025-11-05 14:57

Title

Insecure API Design in danny-avila/librechat

Summary

In danny-avila/librechat version 0.7.9, there is an insecure API design issue in the 2-Factor Authentication (2FA) flow. The system allows users to disable 2FA without requiring a valid OTP or backup code, bypassing the intended verification process. This vulnerability occurs because the backend does not properly validate the OTP or backup code when the API endpoint '/api/auth/2fa/disable' is directly accessed. This flaw can be exploited by authenticated users to weaken the security of their own accounts, although it does not lead to full account compromise.

Severity ?

3.1 (Low)

This flaw can be exploited by authenticated users to weaken the security of their own accounts, although it does not lead to full account compromise."

Vulnerability from cvelistv5 – Published: 2025-10-22 13:54 – Updated: 2025-10-30 18:22

Title

HTML Injection in Accept-Language Header in danny-avila/librechat

Summary

A vulnerability in danny-avila/librechat version 0.7.9 allows for HTML injection via the Accept-Language header. When a logged-in user sends an HTTP GET request with a crafted Accept-Language header, arbitrary HTML can be injected into the <html lang=""> tag of the response. This can lead to potential security risks such as cross-site scripting (XSS) attacks.

Title

Mass Assignment in danny-avila/librechat

Summary

A mass assignment vulnerability exists in danny-avila/librechat, affecting all versions. This vulnerability allows attackers to manipulate sensitive fields by automatically binding user-provided data to internal object properties or database fields without proper filtering. As a result, any extra fields in the request body are included in agentData and passed to the database layer, allowing overwriting of any field in the schema, such as author, access_level, isCollaborative, and projectIds. Additionally, the Object.Prototype can be polluted due to the use of Object.assign with spread operators.

Severity ?

4.3 (Medium)

CVE-2025-7106 (GCVE-0-2025-7106)

Vulnerability from cvelistv5 – Published: 2025-09-23 09:54 – Updated: 2025-09-23 19:29

Title

Authorization Bypass due to Incorrect Access Control in danny-avila/librechat

Summary

danny-avila/librechat is affected by an authorization bypass vulnerability due to improper access control checks. The `checkAccess` function in `api/server/middleware/roles/access.js` uses `permissions.some()` to validate permissions, which incorrectly grants access if only one of multiple required permissions is present. This allows users with the 'USER' role to create agents despite having `CREATE: false` permission, as the check for `['USE', 'CREATE']` passes with just `USE: true`. This vulnerability affects other permission checks as well, such as `PROMPTS`. The issue is present in all versions prior to the fix.

This allows users with the \u0027USER\u0027 role to create agents despite having `CREATE: false` permission, as the check for `[\u0027USE\u0027, \u0027CREATE\u0027]` passes with just `USE: true`. This vulnerability affects other permission checks as well, such as `PROMPTS`. The issue is present in all versions prior to the fix."

CVE-2025-6088 (GCVE-0-2025-6088)

Vulnerability from cvelistv5 – Published: 2025-09-11 00:43 – Updated: 2025-09-11 14:42

Title

Improper Authorization in danny-avila/librechat

Summary

In version 0.7.8 of danny-avila/librechat, improper authorization controls in the conversation sharing feature allow unauthorized access to other users' conversations if the conversation ID is known. Although UUIDv4 conversation IDs are generated server-side and are difficult to brute force, they can be obtained from less-protected sources such as server-side access logs, browser history, or screenshots. The vulnerability permits a logged-in user to gain read-only access to another user's conversations by exploiting the `/api/share/conversationID` endpoint, which lacks authorization checks. This issue is resolved in version v0.7.9-rc1.

Severity ?

4.2 (Medium)

CVE-2025-54868 (GCVE-0-2025-54868)

Vulnerability from cvelistv5 – Published: 2025-08-05 04:53 – Updated: 2025-08-05 16:19

Title

LibreChat exposes arbitrary chats through Meilisearch engine

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.0.6 through 0.7.7-rc1, an exposed testing endpoint allows reading arbitrary chats directly from the Meilisearch engine. The endpoint /api/search/test allows for direct access to stored chats in the Meilisearch engine without proper access control. This results in the ability to read chats from arbitrary users. This issue is fixed in version 0.7.7.

Severity ?

7.5 (High)

Vulnerability from fkie_nvd - Published: 2025-11-29 02:15 - Updated: 2025-12-03 21:49

Severity ?

8.1 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N

Summary

LibreChat is a ChatGPT clone with additional features. Prior to version 0.8.1-rc2, LibreChat is vulnerable to Server-side Request Forgery (SSRF), by passing specially crafted OpenAPI specs to its "Actions" feature and making the LLM use those actions. It could be used by an authenticated user with access to this feature to access URLs only accessible to the LibreChat server (such as cloud metadata services, through which impersonation of the server might be possible). This issue has been patched in version 0.8.1-rc2.

FKIE_CVE-2025-8849

Vulnerability from fkie_nvd - Published: 2025-10-31 00:15 - Updated: 2025-11-10 17:14

Severity ?

7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Summary

LibreChat version 0.7.9 is vulnerable to a Denial of Service (DoS) attack due to unbounded parameter values in the `/api/memories` endpoint. The `key` and `value` parameters accept arbitrarily large inputs without proper validation, leading to a null pointer error in the Rust-based backend when excessively large values are submitted. This results in the inability to create new memories, impacting the stability of the service.

FKIE_CVE-2025-8850

Vulnerability from fkie_nvd - Published: 2025-10-30 20:15 - Updated: 2025-11-19 15:27

Severity ?

8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In danny-avila/librechat version 0.7.9, there is an insecure API design issue in the 2-Factor Authentication (2FA) flow. The system allows users to disable 2FA without requiring a valid OTP or backup code, bypassing the intended verification process. This vulnerability occurs because the backend does not properly validate the OTP or backup code when the API endpoint '/api/auth/2fa/disable' is directly accessed. This flaw can be exploited by authenticated users to weaken the security of their own accounts, although it does not lead to full account compromise.

FKIE_CVE-2025-8848

Vulnerability from fkie_nvd - Published: 2025-10-22 14:15 - Updated: 2025-10-30 17:34

Severity ?

5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N

Summary

A vulnerability in danny-avila/librechat version 0.7.9 allows for HTML injection via the Accept-Language header. When a logged-in user sends an HTTP GET request with a crafted Accept-Language header, arbitrary HTML can be injected into the <html lang=""> tag of the response. This can lead to potential security risks such as cross-site scripting (XSS) attacks.

FKIE_CVE-2025-7104

Vulnerability from fkie_nvd - Published: 2025-09-29 17:15 - Updated: 2025-10-16 16:45

Severity ?

7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

Summary

A mass assignment vulnerability exists in danny-avila/librechat, affecting all versions. This vulnerability allows attackers to manipulate sensitive fields by automatically binding user-provided data to internal object properties or database fields without proper filtering. As a result, any extra fields in the request body are included in agentData and passed to the database layer, allowing overwriting of any field in the schema, such as author, access_level, isCollaborative, and projectIds. Additionally, the Object.Prototype can be polluted due to the use of Object.assign with spread operators.

FKIE_CVE-2025-7106

Vulnerability from fkie_nvd - Published: 2025-09-23 10:15 - Updated: 2025-10-20 19:00

Severity ?

5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N

Summary

danny-avila/librechat is affected by an authorization bypass vulnerability due to improper access control checks. The `checkAccess` function in `api/server/middleware/roles/access.js` uses `permissions.some()` to validate permissions, which incorrectly grants access if only one of multiple required permissions is present. This allows users with the 'USER' role to create agents despite having `CREATE: false` permission, as the check for `['USE', 'CREATE']` passes with just `USE: true`. This vulnerability affects other permission checks as well, such as `PROMPTS`. The issue is present in all versions prior to the fix.

FKIE_CVE-2025-6088

Vulnerability from fkie_nvd - Published: 2025-09-11 01:15 - Updated: 2025-10-16 16:00

Severity ?

3.1 (Low) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N

Summary

In version 0.7.8 of danny-avila/librechat, improper authorization controls in the conversation sharing feature allow unauthorized access to other users' conversations if the conversation ID is known. Although UUIDv4 conversation IDs are generated server-side and are difficult to brute force, they can be obtained from less-protected sources such as server-side access logs, browser history, or screenshots. The vulnerability permits a logged-in user to gain read-only access to another user's conversations by exploiting the `/api/share/conversationID` endpoint, which lacks authorization checks. This issue is resolved in version v0.7.9-rc1.

FKIE_CVE-2025-54868

Vulnerability from fkie_nvd - Published: 2025-08-05 05:15 - Updated: 2025-08-26 13:41

Severity ?

7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Summary

LibreChat is a ChatGPT clone with additional features. In versions 0.0.6 through 0.7.7-rc1, an exposed testing endpoint allows reading arbitrary chats directly from the Meilisearch engine. The endpoint /api/search/test allows for direct access to stored chats in the Meilisearch engine without proper access control. This results in the ability to read chats from arbitrary users. This issue is fixed in version 0.7.7.
