Deeper analysis

XWiki is a generic wiki platform affected by an authorization flaw tracked as CVE-2025-32973. In releases 15.9-rc-1 through 15.10.11, 16.0.0-rc-1 through 16.4.2, and 16.5.0-rc-1 through 16.7.x, the platform fails to display any warning when a user holding programming rights edits a page whose most recent author lacked those rights yet contains an XWiki.ComponentClass object; the edit therefore silently confers programming rights on the object. The issue is classified under CWE-862 and carries a CVSS 3.1 score of 9.0.

An attacker who possesses only edit rights on a single page can insert a malicious ComponentClass object and then rely on any administrator or programming-rights user subsequently editing that page to activate the object, thereby obtaining full programming rights on the wiki. No other interaction or privilege escalation path is required beyond the initial placement and the subsequent edit by a privileged user.

Public advisories and the accompanying patches state that the vulnerability is resolved in XWiki 15.10.12, 16.4.3, and 16.8.0-rc-1. The fix and associated commit are documented in the GitHub Security Advisory GHSA-x7wv-5qg4-vmr6 and the linked XWiki Jira ticket XWIKI-22460.

EPSS for the CVE rose from a low baseline to a peak of 0.0224 on 2026-02-24 before receding to the current value of 0.0058, indicating a measurable increase in exploitation interest after disclosure.

Vulnerability details

XWiki is a generic wiki platform. In versions starting from 15.9-rc-1 to before 15.10.12, from 16.0.0-rc-1 to before 16.4.3, and from 16.5.0-rc-1 to before 16.8.0-rc-1, when a user with programming rights edits a document in XWiki that was last edited…

more

by a user without programming rights and contains an XWiki.ComponentClass, there is no warning that this will grant programming rights to this object. An attacker who created such a malicious object could use this to gain programming rights on the wiki. For this, the attacker needs to have edit rights on at least one page to place this object and then get an admin user to edit that document. This issue has been patched in versions 15.10.12, 16.4.3, and 16.8.0-rc-1.
