CVE-2025-49585 XWiki does not require right warnings for XClass definitions

What is CVE-2025-49585?

CVE-2025-49585 is a high-severity code injection vulnerability in Xwiki Xwiki, published on 13 Jun 2025. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

Official description

XWiki is a generic wiki platform. In versions before 15.10.16, 16.0.0-rc-1 through 16.4.6, and 16.5.0-rc-1 through 16.10.1, when an attacker without script or programming right creates an XClass definition in XWiki (requires edit right), and that same document is later edited by a user with script, admin, or programming right, malicious code could be executed with the rights of the editing user without prior warning. In particular, this concerns custom display code, the script of computed properties and queries in database list properties. Note that warnings before editing documents with dangerous properties have only been introduced in XWiki 15.9, before that version, this was a known issue and the advice was simply to be careful. This has been patched in XWiki 16.10.2, 16.4.7 and 15.10.16 by adding an analysis for the respective XClass properties.
