## What is CVE-2026-77142?

CVE-2026-77142 is a high-severity missing authorization vulnerability in TYPO3 Extension "Industry Directory", published on 25 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The frontend company self-service editing feature relies on a template-level visibility flag to hide the edit form for company records a visitor does not own, but the corresponding write operation does not repeat this ownership check on the server side. As a result, a visitor who knows the identifier of a company record from the public directory can submit a modified update request for that record directly and overwrite its data, without the application ever confirming that the visitor owns it.

Weakness: CWE-862 (Missing Authorization), CWE-639 (Authorization Bypass Through User-Controlled Key)
