CVE-2025-59014· NVD / CVE Program· CNA TYPO3

Denial of Service in TYPO3 Bookmark Toolbar

Noroxi assessment

Priority: Monitor (action score 20/100)

  • 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: 0.29% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: TYPO3 TYPO3 CMS 11.5.48, 12.4.37, 13.4.18.

Low priority for now. Upgrade to TYPO3 TYPO3 CMS 11.5.48, 12.4.37, 13.4.18 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An uncaught exception in the Bookmark Toolbar of TYPO3 CMS versions 11.0.0–11.5.47, 12.0.0–12.4.36, and 13.0.0–13.4.17 lets administrator‑level backend users trigger a denial‑of‑service condition in the backend user interface by saving manipulated data in the bookmark toolbar.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
