Description
The issue exists due to improper escaping in the "Cancel and return to page" button, allowing a remote attacker to execute arbitrary Groovy, Python, or Velocity code, leading to full access to the XWiki installation. Any user with view rights on
XWiki.AttachmentSelector can exploit this. The root cause is related to the improper neutralization of special elements.Recommendations
For versions prior to 13.10.11, update to version 13.10.11 or later.
For versions prior to 14.4.8, update to version 14.4.8 or later.
For versions prior to 14.10.1, update to version 14.10.1 or later.
For versions prior to 15.0-rc-1, update to version 15.0-rc-1 or later.
As a temporary workaround, consider restricting access to
XWiki.AttachmentSelector to minimize the risk of exploitation.Exploit
