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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-22","CWE-59"],"references":["https://github.com/tinacms/tinacms/commit/f124eabaca10dac9a4d765c9e4135813c4830955","https://github.com/tinacms/tinacms/security/advisories/GHSA-g9c2-gf25-3x67","https://github.com/tinacms/tinacms/security/advisories/GHSA-g9c2-gf25-3x67"],"products":["ssw:tinacms\\/graphql"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34604","score":0.00379,"percentile":0.31849,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-g9c2-gf25-3x67","url":"https://osv.dev/vulnerability/GHSA-g9c2-gf25-3x67","summary":"@tinacms/graphql's `FilesystemBridge` Path Validation Can Be Bypassed via Symlinks or Junctions","modified":"2026-04-06T17:04:10.068665Z","packages":[{"ecosystem":"npm","name":"@tinacms/graphql","purl":"pkg:npm/%40tinacms/graphql","ranges":["<2.2.2"],"fixed":["2.2.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
