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. Other endpoint, parameter, role or implementation details not named in this export are not established by this record. Affected versions: before 7.9.2.
