• CVE-2026-52800: 0.25% estimated exploitation activity in the next 30 days; percentile 16.22 (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 In Gogs 0.14.1, organization team member management can be performed via GET requests without CSRF protection. If a victim who is an organization owner is logged in and is tricked into visiting a crafted link, an attacker-controlled user can be added to the Owners team. As a result, the attacker gains organization owner–equivalent privileges. --- Description When a victim is logged in as an organization owner, team member management endpoints are exposed via routes reachable by GET requests, allowing state-changing operations without a CSRF token. Team action route allows GET internal/cmd/web.go:390 CSRF validation is applied only to POST requests Because the global CSRF check is limited to POST requests, state-changing operations reached via GET bypass CSRF protection entirely. internal/context/auth.go:56-61 TeamsAction performs state changes regardless of HTTP method TeamsAction does not branch on the HTTP method. Instead, it performs state-changing operations (such as…

# Patch Next advisory brief: CVE-2026-52800

Advisory: Gogs Vulnerable to CSRF Leading to Organization Owner Takeover
IDs: CVE-2026-52800, GHSA-pwx3-qcgw-vh7h
Record: https://patchnext.com/advisories/cve-2026-52800 (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: High (CVSS 8.8)
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 < 0.14.3; 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-pwx3-qcgw-vh7h (GitHub-reviewed advisory GHSA-pwx3-qcgw-vh7h lists affected ranges: Go gogs.io/gogs >=0 <0.14.3)
