Prior to version 2.2.2, @tinacms/cli recently added lexical path-traversal checks to the dev media routes, but the implementation still validates only the path string and does not resolve symlink or junction targets. If a link already exists under the media root, Tina accepts a path like pivot/written-from-media.txt as \"inside\" the media directory and then performs real filesystem operations through that link target. This allows out-of-root media listing and write access, and the same root cause also affects delete. This issue has been patched in version 2.2.2."}], "lastModified": "2026-04-07T19:13:12.523", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:ssw:tinacms\\/cli:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "F5AA927F-8F0A-485A-B09B-46FE8C12D5B3", "versionEndIncluding": "2.2.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
