Gitea allows attackers to add attachments with forbidden file extensions
CVE-2025-68939GHSA-263q-5cv3-xq9g
What to do
Vendor fix available. Upgrade each affected package to the fixed version on its release line (code.gitea.io/gitea 1.23.0-rc0), redeploy, then verify what is actually installed.
This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2025-68939 Advisory: Gitea allows attackers to add attachments with forbidden file extensions IDs: CVE-2025-68939, GHSA-263q-5cv3-xq9g Record: https://patchnext.com/advisories/cve-2025-68939 (revision 2, source checked 4 Nov 2026, 06:30 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: High (CVSS 8.2) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor fix available; fixed versions by package: code.gitea.io/gitea 1.23.0-rc0. A vendor fix does not mean a deployment is fixed. ## Affected components - Go code.gitea.io/gitea: affected < 1.23.0-rc0; fixed in 1.23.0-rc0 ## Suggested inspection (read-only) - Go code.gitea.io/gitea: check the installed version with your package manager. ## Supported action Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on code.gitea.io/gitea. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://github.com/advisories/GHSA-263q-5cv3-xq9g (GitHub-reviewed advisory GHSA-263q-5cv3-xq9g lists affected ranges: Go code.gitea.io/gitea >=0 <1.23.0-rc0) - Verified: https://osv.dev/vulnerability/GHSA-263q-5cv3-xq9g (OSV record GHSA-263q-5cv3-xq9g lists affected ranges: Go code.gitea.io/gitea >=0 <1.23.0-rc0 (fixed)) Commands are suggestions: review each one before running it.
