Unauthenticated privilege escalation in WP BASE Booking <=5.9.0 lets attackers gain full WordPress site control.
Vulnerability
The WP BASE Booking plugin for WordPress versions 5.9.0 and earlier contains an unauthenticated privilege escalation vulnerability [1]. No authentication or special configuration is required for the vulnerable code path to be reachable, making it accessible to any remote attacker.
Exploitation

The attack requires no prior authentication, user interaction, or elevated network position, enabling automated mass exploitation campaigns [1].
Impact
