CVE-2025-3766Login Lockdown & Protection <= 2.11 - Missing Authorization to Authenticated (Subscriber+) Arbitrary IP Whitelisting
Medium 5.4
In plain English
A medium-severity missing authorization in Login Lockdown & Protection from webfactory. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 26% of all known vulnerabilities).
Official description
The Login Lockdown & Protection plugin for WordPress is vulnerable to unauthorized nonce access due to a missing capability check on the ajax_run_tool function in all versions up to, and including, 2.11. This makes it possible for authenticated attackers, with Subscriber-level access and above, to obtain a valid nonce that can be used to generate a global unlock key, which can in turn be used to add arbitrary IP address to the plugin allowlist. This can only by exploited on new installations where the site administrator hasn't visited the loginlockdown page yet.
