CVE-2026-47352: TYPO3 CMS - Broken Access Control in Backend API

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: TYPO3 TYPO3 CMS 10.4.57, 11.5.51, 12.4.46.

Low priority for now. Upgrade to TYPO3 TYPO3 CMS 10.4.57, 11.5.51, 12.4.46 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Authenticated backend users were able to retrieve file metadata via several Backend API routes without proper permission checks, allowing access to files outside their permitted file mounts or storages. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.
