Published January 23, 2026Updated February 3, 2026Source: osv

Summary

### Impact A reflected cross site scripting (XSS) vulnerability in XWiki allows an attacker to execute arbitrary actions in XWiki with the rights of the victim if the attacker manages to trick a victim into visiting a crafted URL. If the victim has administrative or programming rights, those rights can be exploited to gain full access to the XWiki installation. ### Patches This vulnerability has been patched in XWiki 17.8.0RC1, 17.4.5 and 16.10.12. ### Workarounds The [patch](https://github.com/xwiki/xwiki-platform/commit/8337ac8c3b19c37f306723b638b2cae8b0a57dbf#diff-8f16efedd19baae025db602d8736a105bfd8f72676af2c935b8195a0c356ee71) can be applied manually, only a single line in `templates/logging_macros.vm` needs to be changed, no restart is required. ### References * https://github.com/xwiki/xwiki-platform/commit/8337ac8c3b19c37f306723b638b2cae8b0a57dbf * https://jira.xwiki.org/browse/XWIKI-23462 ### Attribution We thank Mike Cole @mikecole-mg for discovering and reporting this vulnerability.
