GHSA-phwm-87rg-27qq: XWiki Platform vulnerable to reflected cross-site scripting via delattachment action

Impact

It’s possible to perform an XSS by forging a request to a delete attachment action with a specific attachment name. Now this XSS can be exploited only if the attacker knows the CSRF token of the user, or if the user ignores the warning about the missing CSRF token.

Patches

The vulnerability has been patched in XWiki 15.1-rc-1 and XWiki 14.10.6.

Workarounds

There’s no workaround for this other than upgrading XWiki.
