# Patch Next advisory brief: CVE-2025-60633

Advisory: Free5GC is vulnerable to DoS via the Nudm_SubscriberDataManagement API
IDs: CVE-2025-60633, GHSA-3j9f-7w24-pcqg
Record: https://patchnext.com/advisories/cve-2025-60633 (revision 1, source checked 26 Oct 2026, 15:13 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: github.com/free5gc/openapi 1.2.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/free5gc/openapi: affected < 1.2.2; fixed in 1.2.2
- Go github.com/free5gc/udm: affected <= 1.4.0

## Suggested inspection (read-only)
- Go github.com/free5gc/openapi: check the installed version with your package manager.
- Go github.com/free5gc/udm: 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/free5gc/openapi, github.com/free5gc/udm.
- 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-3j9f-7w24-pcqg (GitHub-reviewed advisory GHSA-3j9f-7w24-pcqg lists affected ranges: Go github.com/free5gc/udm >=0 =0 <1.2.2)
