Summary

The LiteSpeed Cache WordPress plugin before 7.9.2 does not check user capabilities in its admin-notice dismissal handler (CWE-862). A nonce that is not tied to a specific notice lets a low-privileged authenticated user, such as a Subscriber, dismiss notices the plugin marks as not dismissible on some site configurations. This includes a warning that sensitive files may be publicly accessible. The references link a public exploit.

Description from the CNA

The LiteSpeed Cache WordPress plugin before 7.9.2 does not perform a capability check on its admin-notice dismissal handler, and the nonce it relies on is not bound to the specific notice being dismissed, so on sites in certain configurations a low-privileged authenticated user (Subscriber) can dismiss administrative notices the LiteSpeed Cache WordPress plugin before 7.9.2 marks as non-dismissible, including a warning that sensitive files may be publicly accessible.
