What is CVE-2024-31996?

The XWiki Platform contains a vulnerability in its HTML escaping tool, which fails to appropriately escape the { character. This oversight potentially allows for XWiki syntax injection, resulting in remote code execution by an attacker. The issue exists in XWiki versions 3.0.1 and prior to 4.10.19, 15.5.4, and 15.10-rc-1. To remediate the vulnerability, users are advised to upgrade to the patched versions. Alternatively, a temporary fix involves replacing $escapetool.html with $escapetool.xml within specific XWiki documents. Notably, the panel document Panels.PanelLayoutUpdate has been identified as one that exposes this vulnerability, but other extensions may also be susceptible and could require attention.
