CVE-2025-55729Public exploitNetwork attack vector

Authenticated code execution via unescaped layout type

Published Sep 9, 2025 · Updated Sep 10, 2025

XWiki Pro Macros before 1.26.5 allows remote authenticated users to execute code by editing a page with a crafted layout macro. ConfluenceLayoutSection copies the attacker-controlled ac:type value into cssLayoutClass and embeds it unescaped in XWiki 2.1 syntax. Page-edit permission is sufficient to inject XWiki syntax that invokes Groovy and execute code in the XWiki server context.
