CVE-2024-31996Public exploitNetwork attack vector

Unauthenticated code execution via incomplete HTML escaping

Published Apr 10, 2024 · Updated Aug 2, 2024

Code injection in affected XWiki Commons releases allows remote attackers to execute code through crafted curly-brace sequences. The EscapeTool.html method uses generic HTML escaping that leaves XWiki syntax delimiters intact, so injected syntax reaches dynamic Velocity evaluation. A standard XWiki installation exposes the flaw through Panels.PanelLayoutUpdate without authentication, granting programming rights and full server code execution.
