Prior to 8.31.0, Gotenberg only checks if the tag is exactly FileName, so System:FileName slips right through and ExifTool happily renames the file. This allows remote attackers to move, rename, and change permissions for arbitrary files. This vulnerability is fixed in 8.31.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","score":8.2},"cwes":["CWE-73","CWE-184"],"references":["https://github.com/gotenberg/gotenberg/security/advisories/GHSA-62p3-hvxx-fxg4","https://github.com/gotenberg/gotenberg/security/advisories/GHSA-62p3-hvxx-fxg4"],"products":["thecodingmachine:gotenberg"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-40893","score":0.00347,"percentile":0.28306,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-62p3-hvxx-fxg4","url":"https://osv.dev/vulnerability/GHSA-62p3-hvxx-fxg4","summary":"Gotenberg has an ExifTool Dangerous Tag Blocklist Bypass via Group-Prefixed Tag Names that Allows Arbitrary File Rename and Move","modified":"2026-06-25T18:56:20.819995944Z","packages":[{"ecosystem":"Go","name":"github.com/gotenberg/gotenberg/v8","purl":"pkg:golang/github.com/gotenberg/gotenberg/v8","ranges":["<=8.30.1"],"fixed":[]}]},{"id":"GO-2026-5162","url":"https://osv.dev/vulnerability/GO-2026-5162","summary":"Gotenberg has an ExifTool Dangerous Tag Blocklist Bypass via Group-Prefixed Tag Names that Allows Arbitrary File Rename and Move in github.com/gotenberg/gotenberg","modified":"2026-06-25T18:45:27.407349969Z","packages":[{"ecosystem":"Go","name":"github.com/gotenberg/gotenberg/v7","purl":"pkg:golang/github.com/gotenberg/gotenberg/v7","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/gotenberg/gotenberg/v8","purl":"pkg:golang/github.com/gotenberg/gotenberg/v8","ranges":["all versions"],"fixed":[]}]}],"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).
