AnalysisAI
Unauthenticated blind SQL injection in the WordPress plugin WP BASE Booking (wp-base-booking-of-appointments-services-and-events) in all versions up to and including 6.4.0 lets remote attackers inject arbitrary SQL into database queries by manipulating request parameters handled by the plugin. Because the CVSS vector is AV:N/AC:L/PR:N/UI:N, no credentials, user interaction, or special configuration are required - any site with the plugin installed and reachable over the network is exposed, and exploitation is limited only by the fact that the injection is blind, so data must be extracted through boolean or time-based inference rather than direct query output. …
