Technical details

A Cross-Site Request Forgery (CSRF) vulnerability exists in the Simple Link Directory Pro plugin for WordPress due to missing nonce validation on sensitive administrative functions. An unauthenticated remote attacker can exploit this by crafting a malicious request and tricking a site administrator into executing it via social engineering (e.g., a malicious link). Successful exploitation allows the attacker to perform unauthorized state-changing actions, such as modifying directory settings or deleting entries, impacting the integrity and availability of the plugin's data. The issue is addressed in version 15.0.9.
