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 content root, a path like content/posts/pivot/owned.md is still considered \"inside\" the base even though the real filesystem target can be outside it. As a result, FilesystemBridge.get(), put(), delete(), and glob() can operate on files outside the intended root. This issue has been patched in version 2.2.2."}], "lastModified": "2026-04-07T19:08:26.790", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:ssw:tinacms\\/graphql:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "C7C5E716-5EA4-499D-B5C0-864632E2620D", "versionEndIncluding": "2.2.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
