# Patch Next advisory brief: CVE-2025-48201 Advisory: The Backup Plus extension for TYPO3 (ns_backup) has a Predictable Resource Location IDs: CVE-2025-48201, GHSA-hq4f-5qjv-fwrg Record: https://patchnext.com/advisories/cve-2025-48201 (revision 1, source checked 26 Oct 2026, 14:33 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: High (CVSS 8.6) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor fix available; fixed versions by package: nitsan/ns-backup 13.0.1. A vendor fix does not mean a deployment is fixed. ## Affected components - Packagist nitsan/ns-backup: affected < 13.0.1; fixed in 13.0.1 ## Suggested inspection (read-only) - Packagist nitsan/ns-backup: 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 nitsan/ns-backup. - 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-hq4f-5qjv-fwrg (GitHub-reviewed advisory GHSA-hq4f-5qjv-fwrg lists affected ranges: Packagist nitsan/ns-backup >=0 <13.0.1) Commands are suggestions: review each one before running it.
