## FAQ

### What does this mean?

A user with low privileges can become an administrator and gain full control of the site. The flaw lets a Subscriber-level account raise its own privileges.

### Am I affected, and how do I check?

Versions 6.5.2 and earlier of the WP BASE Booking plugin are listed as vulnerable. The condition is that the attacker holds a Subscriber account on the site. To check a site, look up the installed plugin version on the WordPress Plugins page.

### What should I do about it?

The checked facts do not name a fixed version. Update to a release newer than 6.5.2 once the vendor publishes one, and check the plugin's official page for the current release.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What if there's no patch?

The checked facts give no workaround. The one setup condition they name is the Subscriber account requirement, so reviewing which users hold Subscriber accounts is the only limit the facts support until a fix is released.
