CVE-2026-78393
UnknownSummary
The Link Library WordPress plugin before 7.9.6 does not properly escape some parameters before outputting them in the addresses of links it generates on its front-end directory pages. This leads to Reflected Cross-Site Scripting (XSS) which could be used against any visitor, including logged-in administrators.
Risk Assessment
An attacker can execute arbitrary JavaScript in a victim's browser, potentially hijacking an administrator session. This may lead to credential theft or unauthorized actions.
Recommendation
Upgrade the Link Library plugin to version 7.9.6 or later. Consider implementing security headers such as Content-Security-Policy to mitigate XSS impact.

The Link Library WordPress plugin before 7.9.6 does not validate the destination of a user-supplied URL before falling back to an unprotected fetch when its safe request is rejected.
