• CVE-2025-64719: 0.44% estimated exploitation activity in the next 30 days; percentile 38.31 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary A malicious user with rights to create a new file on a repository or wiki page can trigger a denial of service condition in which the pages containing the listing of files will return HTTP error 500 and render the web interface unusable for the repository or wiki. Details The issue is present in file internal/route/repo/wiki.go and internal/route/repo/view.go where the pages try to recover commit information. If errors are returned while recovering commit information, the page will return a 500 error and stop rendering, resulting in a denial of service. In view.go the issue occurs at line 56 while a slightly different issue occurs in wiki.go at line 174 where commits[0] is dereferenced without checking if it contains value. It is possible to trigger issues in assigning the correct value to variable commits by using a specific string as part of the page title. The issue is linked to the fact that file names can contain special characters such as , ?, [, ], etc. that will be…

# Patch Next advisory brief: CVE-2025-64719

Advisory: Gogs has a Denial of Service in repository/wiki file listing web pages
IDs: CVE-2025-64719, GHSA-3qq3-668m-v9mj
Record: https://patchnext.com/advisories/cve-2025-64719 (revision 1, source checked 26 Oct 2026, 15:27 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: gogs.io/gogs 0.14.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go gogs.io/gogs: affected <= 0.14.2; fixed in 0.14.3

## Suggested inspection (read-only)
- Go gogs.io/gogs: 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 gogs.io/gogs.
- 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-3qq3-668m-v9mj (GitHub-reviewed advisory GHSA-3qq3-668m-v9mj lists affected ranges: Go gogs.io/gogs >=0 <=0.14.2)
