AI-suggested
Users should monitor the vendor's advisory for an official fix. Until a patch is available, restrict access to trusted users only and consider disabling or removing the 6Storage Rentals plugin to prevent exploitation. Avoid relying on the plugin in environments where Subscriber-level users exist.
Description
The 6Storage Rentals WordPress plugin up to version 2.31.0 contains an authentication bypass vulnerability allowing users with Subscriber-level access or higher to authenticate as any existing WordPress user, including administrators. This occurs due to missing capability checks and nonce verification in AJAX handlers that allow attacker-controlled data to influence authentication state, leading to full site compromise. The issue is a partial fix of a prior vulnerability and remains exploitable.
