# Patch Next advisory brief: CVE-2025-11275 Advisory: PYSEC-2025-156 IDs: CVE-2025-11275 Record: https://patchnext.com/advisories/cve-2025-11275 (revision 1, source checked 24 Oct 2026, 04:13 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: High (CVSS 7.8) 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 - PyPI pyassimp: affected <= 6.0.2 ## Suggested inspection (read-only) - `python -m pip show pyassimp`: prints the installed version. Run with the environment that serves production active. ## 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 pyassimp. - 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://osv.dev/vulnerability/PYSEC-2025-156 (OSV record PYSEC-2025-156 lists affected ranges: PyPI pyassimp >=0 <=6.0.2) Commands are suggestions: review each one before running it.
