CVE-2026-49048HighCVSS 8.7CVE published 28 June 2026Added to mySites.guru 17 July 2026

# JoomCCK (com\_joomcck) below 6.4.1 - Unauthenticated SQL Injection

JoomCCK (JoomCoder) versions up to and including 6.4.0 contain an unauthenticated SQL injection (CVE-2026-49048): a front-end controller task concatenates a request parameter directly into two SQL statements with no escaping or parameterisation, so an anonymous visitor can read from the site database. Scored CVSS 4.0 8.7 (High) by the Joomla CNA, and 9.8 (Critical) on the older CVSS 3.1 scale. Reported by Kamil Soltanov (not by mySites.guru). Update to JoomCCK 6.4.1 or later.
