Technical details
The TrueBooker plugin for WordPress (versions 1.1.9 and below) suffers from a broken access control vulnerability due to missing authorization checks (CWE-862). An unauthenticated remote attacker can exploit this flaw by sending crafted requests to vulnerable functions that fail to validate user permissions or nonces. Successful exploitation allows the attacker to execute high-privileged actions, potentially leading to full data compromise or unauthorized modification of site settings. The issue is resolved in version 1.2.0.
