The Link Library WordPress plugin versions before 7.9.4 contain a reflected XSS vulnerability due to improper sanitization and escaping of user-supplied input parameters. An unauthenticated attacker can exploit this by tricking users into performing actions that cause the malicious script to execute in their browsers. This vulnerability is identified as CWE-79 and has a CVSS 3.1 base score of 6.1, indicating a medium severity impact with network attack vector, low attack complexity, no privileges required, user interaction needed, and partial confidentiality and integrity impact.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser session, potentially allowing theft of cookies, session tokens, or other sensitive information accessible to the browser. The vulnerability does not impact availability. The attacker must trick a user into interacting with a crafted link or request.
