CVE-2026-102782: OrdaSoft Simple Membership < 7.4.0 - SQL Injection

id: CVE-2026-102782

info:
  name: OrdaSoft Simple Membership < 7.4.0 - SQL Injection
  author: HaroonArshad-53
  severity: critical
  description: |
    OrdaSoft Simple Membership (com_simplemembership) for Joomla before 7.4.0 is vulnerable to unauthenticated SQL injection via the 'login' parameter of the checkLoginPass task (site/simplemembership.php). The handler passes the value through Joomla's generic input filter, which strips HTML but leaves quotes and SQL syntax intact, and concatenates it directly into the SQL query with no escaping or parameter binding. Error-based injection via extractvalue() lets unauthenticated attackers exfiltrate database contents.
  impact: |
    Unauthenticated attackers can read arbitrary database contents, including Joomla user credentials (usernames, emails, password hashes), session data and membership records, enabling further compromise of the site.
  remediation: |
    Update OrdaSoft Simple Membership to version 7.4.0 or later.
