WordPress Plugin SQL Injection Vulnerabilities

Blind SQL injection in Profile Builder Pro WordPress plugin versions up to 3.13.9 allows remote unauthenticated attackers to extract database contents and cause service degradation. The vulnerability exploits improper input sanitization in SQL queries, enabling attackers to manipulate database commands without authentication. CVSS score of 9.3 (Critical) reflects network-accessible attack surface with no authentication barrier, though EPSS score of 0.03% (8th percentile) indicates minimal observed exploitation attempts. Patchstack database confirms vulnerability details; no CISA KEV listing indicates no confirmed active exploitation at time of analysis.

Unauthenticated attackers can exploit SQL injection in the Simply Schedule Appointments Booking Plugin for WordPress (versions up to 1.6.10.0) through the 'fields' parameter to extract sensitive database information including usernames, email addresses, and password hashes. The vulnerability stems from insufficient input escaping and improper SQL query preparation, allowing attackers to inject arbitrary SQL commands without authentication. No patch is currently available.
