LiteSpeed Cache < 7.9.2 - Subscriber+ Pinned Administrative Notice Dismissal

Description

The plugin 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 plugin marks as non-dismissible, including a warning that sensitive files may be publicly accessible.
