These injected scripts would be executed when users visit the affected site, potentially compromising user data or website functionality (Patchstack).

The vulnerability has been fixed in version 2.2.5 of the Restrict plugin. Site administrators are advised to update to version 2.2.5 or later immediately. For users of Patchstack, a virtual patch has been issued to mitigate this issue by blocking potential attacks until the update can be applied (Patchstack).
