CVE-2026-70594 (GCVE-0-2026-70594)

Vulnerability from nvd – Published: 2026-08-04 21:53 – Updated: 2026-08-04 21:53

Title

Ghost: Session Fixation in Ghost Admin

Summary

Ghost is a Node.js content management system. From 2.2.0 until 6.54.1, Ghost Admin did not invalidate existing sessions on login which could have allowed for session fixation attacks. Successful exploitation would have required another vulnerability on the same domain where Ghost Admin was hosted. This issue is fixed in version 6.54.1.

Severity

6.7 (Medium)

Title

Ghost: Blind Password Hash Disclosure in Ghost Admin API

Summary

Ghost is a Node.js content management system. Prior to 6.54.1, any staff-level user was able to leak the hashed passwords of other staff users through the Ghost Admin API. An offline password-guessing attack against the hashes could lead to account takeover if successful, but Device Verification should have prevented an attacker from logging in with a recovered password. Depending on the database used, leaked hashes may not have had the correct casing for all characters, increasing the difficulty of a password-guessing attack. This issue is fixed in version 6.54.1.

Severity

4.8 (Medium)

CVE-2026-25552 (GCVE-0-2026-25552)

Vulnerability from nvd – Published: 2026-07-31 18:12 – Updated: 2026-07-31 19:00 X_Open Source

Title

Ghost CLI < 1.30.1 IP Spoofing via X-Forwarded-For Header

Summary

Ghost CLI before 1.30.1 contains an IP spoofing vulnerability that allows unauthenticated remote attackers to bypass rate-limiting controls by manipulating the X-Forwarded-For header through a misconfigured Nginx configuration. Attackers can append attacker-controlled values to the header chain using the $proxy_add_x_forwarded_for directive to present an arbitrary IP address, circumventing Ghost's rate-limiting mechanisms on self-hosted instances.

Ghost: Paid gift memberships obtainable at minimal cost via the donations feature

Summary

Ghost is a Node.js content management system. From 6.27.0 before 6.44.0, Ghost's public donation checkout flow allowed an unauthenticated attacker to control donation checkout metadata and obtain full paid gift memberships for a minimal payment without exposing customer or member data or stealing money from a site or its members. This issue is fixed in version 6.44.0.

CVE-2026-53949 (GCVE-0-2026-53949)

Vulnerability from nvd – Published: 2026-06-24 18:05 – Updated: 2026-06-24 18:55

Title

Ghost Content API filter bypass reveals private fields

Summary

Ghost is a Node.js content management system. From 5.46.1 until 6.21.2, the validation applied to filters on the public API endpoints could be partially bypassed, making it possible to reveal private fields via a brute force attack. If SQLite was used as the database password hashes were fully accessible. If MySQL was used as the database the password hashes' case (uppercase / lowercase) would have been lost, which would likely have rendered a further brute force attack on the discovered hashes fruitless. This vulnerability is fixed in 6.21.2.

Severity

5.3 (Medium)

Title

Ghost: File Upload Content-Type Spoofing

Summary

Ghost is a Node.js content management system. From 6.19.4 until 6.21.1, insufficient validation of the client-supplied Content-Type on Ghost's Admin API file upload endpoint allowed uploaded files to be served from the site with an attacker-chosen content type on S3/GCS storage backends. On installations that serve uploaded files from the same origin as the site, this could have been used to facilitate stored cross-site scripting against site visitors or staff. This vulnerability is fixed in 6.21.1.

Severity

5.4 (Medium)

Title

Ghost: Member existence leak via magic link sign-in response

Summary

Ghost is a Node.js content management system. From 5.18.0 until 6.21.1, a discrepancy in responses from the members signin endpoints made it possible for an unauthenticated attacker to determine whether a given email address belongs to a registered member of a Ghost site. This vulnerability is fixed in 6.21.1.

Severity

CVE-2026-53946 (GCVE-0-2026-53946)

Vulnerability from nvd – Published: 2026-06-24 18:08 – Updated: 2026-06-25 19:57

Title

Ghost: Mobiledoc image-size fetch SSRF

Summary

Ghost is a Node.js content management system. From 6.19.4 until 6.21.1, when re-rendering posts, Ghost would refetch missing image dimensions by issuing an outbound HTTP request to the URL stored on an image card — without restricting that URL to trusted image hosts. An authenticated staff user able to create or edit posts could therefore point an image card at an attacker-chosen host and cause the Ghost server to request it on their behalf, including hosts on internal networks or cloud instance metadata endpoints that would not normally be reachable from the public internet. This vulnerability is fixed in 6.21.1.

Severity

5.4 (Medium)

Ghost: Server-side request forgery via DNS rebinding in external request handling

Summary

Ghost is a Node.js content management system. From 6.0.9 until 6.21.1, Ghost’s private-IP check for outbound HTTP requests could be bypassed via DNS rebinding, allowing an attacker to coerce the Ghost server into reaching hosts on internal networks through features that issue external fetches. This vulnerability is fixed in 6.21.1.

Ghost: Private IP filtering bypass to make server-side requests to internal services

Summary

Ghost is a Node.js content management system. From 6.0.9 until 6.21.1, when making an external request, it is possible to bypass the IP filter that ensures the request isn't going to an internal service using an IPv6 literal which maps to a private IPv4 address. This vulnerability is fixed in 6.21.1.

Severity

5.8 (Medium)

Title

Ghost: Cache-poisoning XSS in Ghost frontend via x-ghost-preview header

Summary

Ghost is a Node.js content management system. From until 6.37.0, when Ghost is behind a shared caching layer that results in cached content being shared between different visitors, an unauthenticated user could send an x-ghost-preview header that altered the rendered frontend response. In affected cache configurations, that response could be stored and served to subsequent visitors requesting the same page, allowing cache poisoning of request-specific preview output. When running Ghost's frontend and admin panel on the same domain this could be used to take over staff user accounts. When running these on different domains staff accounts have no exposure. This vulnerability is fixed in 6.37.0.

Severity

9.6 (Critical)

Ghost: Session Fixation in Ghost Admin

Summary

Ghost is a Node.js content management system. From 2.2.0 until 6.54.1, Ghost Admin did not invalidate existing sessions on login which could have allowed for session fixation attacks. Successful exploitation would have required another vulnerability on the same domain where Ghost Admin was hosted. This issue is fixed in version 6.54.1.

CVE-2026-70590 (GCVE-0-2026-70590)

Vulnerability from cvelistv5 – Published: 2026-08-04 21:27 – Updated: 2026-08-04 21:27

Title

Ghost: Blind Password Hash Disclosure in Ghost Admin API

Summary

Ghost is a Node.js content management system. Prior to 6.54.1, any staff-level user was able to leak the hashed passwords of other staff users through the Ghost Admin API. An offline password-guessing attack against the hashes could lead to account takeover if successful, but Device Verification should have prevented an attacker from logging in with a recovered password. Depending on the database used, leaked hashes may not have had the correct casing for all characters, increasing the difficulty of a password-guessing attack. This issue is fixed in version 6.54.1.

Severity

4.8 (Medium)

Title

Ghost CLI < 1.30.1 IP Spoofing via X-Forwarded-For Header

Summary

Ghost CLI before 1.30.1 contains an IP spoofing vulnerability that allows unauthenticated remote attackers to bypass rate-limiting controls by manipulating the X-Forwarded-For header through a misconfigured Nginx configuration. Attackers can append attacker-controlled values to the header chain using the $proxy_add_x_forwarded_for directive to present an arbitrary IP address, circumventing Ghost's rate-limiting mechanisms on self-hosted instances.

Title

Ghost: Paid gift memberships obtainable at minimal cost via the donations feature

Summary

Ghost is a Node.js content management system. From 6.27.0 before 6.44.0, Ghost's public donation checkout flow allowed an unauthenticated attacker to control donation checkout metadata and obtain full paid gift memberships for a minimal payment without exposing customer or member data or stealing money from a site or its members. This issue is fixed in version 6.44.0.

Severity

5.3 (Medium)

CVE-2026-53943 (GCVE-0-2026-53943)

Vulnerability from cvelistv5 – Published: 2026-06-24 18:13 – Updated: 2026-06-24 18:48

Title

Ghost: Cache-poisoning XSS in Ghost frontend via x-ghost-preview header

Summary

Ghost is a Node.js content management system. From until 6.37.0, when Ghost is behind a shared caching layer that results in cached content being shared between different visitors, an unauthenticated user could send an x-ghost-preview header that altered the rendered frontend response. In affected cache configurations, that response could be stored and served to subsequent visitors requesting the same page, allowing cache poisoning of request-specific preview output. When running Ghost's frontend and admin panel on the same domain this could be used to take over staff user accounts. When running these on different domains staff accounts have no exposure. This vulnerability is fixed in 6.37.0.

Severity

9.6 (Critical)

Ghost: Private IP filtering bypass to make server-side requests to internal services

Summary

Ghost is a Node.js content management system. From 6.0.9 until 6.21.1, when making an external request, it is possible to bypass the IP filter that ensures the request isn't going to an internal service using an IPv6 literal which maps to a private IPv4 address. This vulnerability is fixed in 6.21.1.

Severity

5.8 (Medium)

CVE-2026-53946 (GCVE-0-2026-53946)

Vulnerability from cvelistv5 – Published: 2026-06-24 18:08 – Updated: 2026-06-25 19:57

Title

Ghost: Mobiledoc image-size fetch SSRF

Summary

Ghost is a Node.js content management system. From 6.19.4 until 6.21.1, when re-rendering posts, Ghost would refetch missing image dimensions by issuing an outbound HTTP request to the URL stored on an image card — without restricting that URL to trusted image hosts. An authenticated staff user able to create or edit posts could therefore point an image card at an attacker-chosen host and cause the Ghost server to request it on their behalf, including hosts on internal networks or cloud instance metadata endpoints that would not normally be reachable from the public internet. This vulnerability is fixed in 6.21.1.

Severity

5.4 (Medium)

An authenticated staff user able to create or edit posts could therefore point an image card at an attacker-chosen host and cause the Ghost server to request it on their behalf, including hosts on internal networks or cloud instance metadata endpoints that would not normally be reachable from the public internet. This vulnerability is fixed in 6.21.1."
