CVE-2026-55660 TinaCMS: Cross-origin postMessage handlers and rich-text URL-sanitization bypass enable stored XSS and session takeover

Tina is a headless content management system. In versions prior to @tinacms/app 2.5.6 and tinacms 3.9.3, cross-origin postMessage handlers and a rich-text URL-sanitization bypass enable stored XSS and session takeover. The library registers window message listeners — the useTina overlay handler,...

CVE-2026-55660

CVE-2026-55660 : TinaCMS and Tinacms app prior to versions 2.5.6 / 3.9.3 allow cross-origin postMessage abuse due to window message listeners that do not validate event.origin/source and post to non-specific origins, combined with insufficient URL sanitization in rich-text content. This enables s...

CVE-2026-54074 @tinacms/cli: Remote Code Execution via Forestry migration — unsanitised __TINA_INTERNAL__ marker in user-controlled YAML labels

Tina is a headless content management system. @tinacms/cli versions prior to 2.4.3 contain a Remote Code Execution vulnerability in the Forestry-to-Tina migration command. The internal helper addVariablesToCode unquotes any value matching the marker "TINAINTERNAL:::.?:::" inside the stringified...

CVE-2026-54074

CVE-2026-54074 affects @tinacms/cli (pre-2.4.3) used with TinaCMS.

CVE-2026-33949

Tina is a headless content management system. Prior to version 2.2.2, a path traversal vulnerability in @tinacms/graphql allows unauthenticated users to write and overwrite arbitrary files within the project root. This is achieved by manipulating the relativePath parameter in GraphQL mutations. T...

CVE-2026-34604

Tina is a headless content management system. Prior to version 2.2.2, @tinacms/graphql uses string-based path containment checks in FilesystemBridge. That blocks plain ../ traversal, but it does not resolve symlink or junction targets. If a symlink/junction already exists under the allowed conten...
