Prior to 3.0.0, @tinacms/cli reads Git branch values from VERCEL_GIT_COMMIT_REF, GITHUB_BRANCH, or HEAD, incorporates the raw value into the API URL, and interpolates that URL into JavaScript string literals in packages/@tinacms/cli/src/next/codegen/index.ts and packages/@tinacms/cli/src/next/codegen/codegen/plugin.ts. A crafted Git-valid branch name containing a quote can terminate the generated string and inject an expression that executes when the generated client module is imported during a preview build. The injected code runs with the build process privileges and can read environment credentials, modify deployment artifacts, or make network requests. This issue is fixed in version 3.0.0.\nhttps://www.cve.org/CVERecord?id=CVE-2026-108259https://github.com/tinacms/tinacms/security/advisories/GHSA-pwhx-cvv3-qj5chttps://github.com/tinacms/tinacms/pull/7526https://github.com/tinacms/tinacms/commit/d030d414d39e15de79bf36e4c728d57205e71ddehttps://github.com/tinacms/tinacms/releases/tag/@tinacms/cli@3.0.0#tinacms #@tinacms #cli#CVE_2026_108259#bot", "creation_timestamp": "2026-10-09T20:52:02.125659Z"}, {"uuid": "b8721c54-70b3-4521-bc63-357ff984b49b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-108259", "type": "seen", "source": "https://bsky.app/profile/thehackerwire.bsky.social/post/3mxhx5rfnuu2g", "content": "\ud83d\udfe0 CVE-2026-108259 - High (8.2)\n\nTina is a headless content management system.
