CVE-2024-21635 (GCVE-0-2024-21635)

Title
Memos Access Tokens Stay Valid after User Password Change
Summary
Memos is a privacy-first, lightweight note-taking service that uses Access Tokens to authenticate application access. When a user changes their password, the existing list of Access Tokens stay valid instead of expiring. If a user finds that their account has been compromised, they can update their password. In versions up to and including 0.18.1, though, the bad actor will still have access to their account because the bad actor's Access Token stays on the list as a valid token. The user will have to manually delete the bad actor's Access Token to secure their account. The list of Access Tokens has a generic Description which makes it hard to pinpoint a bad actor in a list of Access Tokens. A known patched version of Memos isn't available. To improve Memos security, all Access Tokens will need to be revoked when a user changes their password. This removes the session for all the user's devices and prompts the user to log in again. One can treat the old Access Tokens as "invalid" because those Access Tokens were created with the older password.

Summary
Memos 0.22 is vulnerable to Stored Cross site scripting (XSS) vulnerabilities by the upload attachment and user avatar features. Memos does not verify the content type of the uploaded data and serve it back as is. An authenticated attacker can use this to elevate their privileges when the stored XSS is viewed by an admin.

CVE-2025-50738 (GCVE-0-2025-50738)
Vulnerability from nvd – Published: 2025-07-29 00:00 – Updated: 2025-08-22 15:36
VLAI?
Summary
The Memos application, up to version v0.24.3, allows for the embedding of markdown images with arbitrary URLs. When a user views a memo containing such an image, their browser automatically fetches the image URL without explicit user consent or interaction beyond viewing the memo. This can be exploited by an attacker to disclose the viewing user's IP address, browser User-Agent string, and potentially other request-specific information to the attacker-controlled server, leading to information disclosure and user tracking.

FKIE_CVE-2024-21635
Vulnerability from fkie_nvd - Published: 2025-11-14 15:15 - Updated: 2025-11-26 16:05
Severity ?
Summary
Memos is a privacy-first, lightweight note-taking service that uses Access Tokens to authenticate application access. When a user changes their password, the existing list of Access Tokens stay valid instead of expiring. If a user finds that their account has been compromised, they can update their password. In versions up to and including 0.18.1, though, the bad actor will still have access to their account because the bad actor's Access Token stays on the list as a valid token. The user will have to manually delete the bad actor's Access Token to secure their account. The list of Access Tokens has a generic Description which makes it hard to pinpoint a bad actor in a list of Access Tokens. A known patched version of Memos isn't available. To improve Memos security, all Access Tokens will need to be revoked when a user changes their password. This removes the session for all the user's devices and prompts the user to log in again. One can treat the old Access Tokens as "invalid" because those Access Tokens were created with the older password.

Summary
Memos 0.22 is vulnerable to Stored Cross site scripting (XSS) vulnerabilities by the upload attachment and user avatar features. Memos does not verify the content type of the uploaded data and serve it back as is. An authenticated attacker can use this to elevate their privileges when the stored XSS is viewed by an admin.

FKIE_CVE-2025-50738
Vulnerability from fkie_nvd - Published: 2025-07-29 15:15 - Updated: 2025-08-22 16:15
Severity ?
Summary
The Memos application, up to version v0.24.3, allows for the embedding of markdown images with arbitrary URLs. When a user views a memo containing such an image, their browser automatically fetches the image URL without explicit user consent or interaction beyond viewing the memo. This can be exploited by an attacker to disclose the viewing user's IP address, browser User-Agent string, and potentially other request-specific information to the attacker-controlled server, leading to information disclosure and user tracking.

Title
Memos Access Tokens Stay Valid after User Password Change
Summary
Memos is a privacy-first, lightweight note-taking service that uses Access Tokens to authenticate application access. When a user changes their password, the existing list of Access Tokens stay valid instead of expiring. If a user finds that their account has been compromised, they can update their password. In versions up to and including 0.18.1, though, the bad actor will still have access to their account because the bad actor's Access Token stays on the list as a valid token. The user will have to manually delete the bad actor's Access Token to secure their account. The list of Access Tokens has a generic Description which makes it hard to pinpoint a bad actor in a list of Access Tokens. A known patched version of Memos isn't available. To improve Memos security, all Access Tokens will need to be revoked when a user changes their password. This removes the session for all the user's devices and prompts the user to log in again. One can treat the old Access Tokens as "invalid" because those Access Tokens were created with the older password.

Vulnerability from cvelistv5 – Published: 2025-07-29 00:00 – Updated: 2025-08-22 15:36

Summary
The Memos application, up to version v0.24.3, allows for the embedding of markdown images with arbitrary URLs. When a user views a memo containing such an image, their browser automatically fetches the image URL without explicit user consent or interaction beyond viewing the memo. This can be exploited by an attacker to disclose the viewing user's IP address, browser User-Agent string, and potentially other request-specific information to the attacker-controlled server, leading to information disclosure and user tracking.
