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 can be applied manually, only a single line in templates/logging_macros.vm needs to be changed, no restart is required.
