DescriptionGitHub Advisory

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Versions 7.0-milestone-2 through 16.10.11, 17.0.0-rc-1 through 17.4.4, and 17.5.0-rc-1 through 17.7.0 contain a reflected Cross-site Scripting (XSS) vulnerability, which allows an attacker to craft a malicious URL and execute arbitrary actions with the same privileges as the victim. If the victim has administrative or programming rights, those rights can be exploited to gain full access to the XWiki installation. This issue has been patched in versions 17.8.0-rc-1, 17.4.5 and 16.10.12. To workaround, the patch can be applied manually, only a single line in templates/logging_macros.vm needs to be changed, no restart is required.

AnalysisAI

Reflected XSS in XWiki Platform versions 7.0 through 17.7.0 enables attackers to craft malicious URLs that execute arbitrary actions with victim privileges, potentially leading to full installation compromise if the victim holds administrative or programming rights. The vulnerability requires user interaction to trigger and affects multiple version branches across the XWiki and XWiki Rendering products. Patches are available for affected versions, and a manual workaround exists that requires modification of a single line in the logging_macros.vm template without requiring a restart.
