CVE-2024-4434: LearnPress WordPress LMS Plugin <= 4.2.6.5 - SQL Injection

id: CVE-2024-4434

info:
  name: LearnPress WordPress LMS Plugin <= 4.2.6.5 - SQL Injection
  author: s4e-io
  severity: critical
  description: |
    The LearnPress WordPress LMS Plugin plugin for WordPress is vulnerable to time-based SQL Injection via the ‘term_id’ parameter in versions up to, and including, 4.2.6.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
  remediation: Fixed in 4.2.6.6
