# Patch Next advisory brief: CVE-2026-6634

Advisory: Memos has an Incorrect Privilege Assignment issue
IDs: CVE-2026-6634, GHSA-gqp3-hfc3-8q54
Record: https://patchnext.com/advisories/cve-2026-6634 (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: Low (CVSS 2.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/usememos/memos: affected <= 0.22.1

## Suggested inspection (read-only)
- Go github.com/usememos/memos: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/usememos/memos.
- 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-gqp3-hfc3-8q54 (GitHub-reviewed advisory GHSA-gqp3-hfc3-8q54 lists affected ranges: Go github.com/usememos/memos >=0 <=0.22.1)
