What we check for

CVE-2026-66914

SEBLOD (com_cck) below 3.30.0 - Unauthenticated Path Traversal Arbitrary File Download (CVE-2026-66914, CVSS 9.2)

SEBLOD versions 1.0.0 to 3.29.0 (the Joomla 3 branch) contain an unauthenticated path traversal flaw (CWE-22). No login, no token and no permissions are required: an attacker can request arbitrary paths and download files from inside AND outside the web root, including configuration.php with your database credentials, and site backups or logs sitting above the document root. CVSS 4.0 base score 9.2 (Critical), reported by Krzysztof Zajac of CERT PL and published by the Joomla CNA on 7 August 2026. Update SEBLOD to 3.30.0 or later. There is no vendor-published workaround; if you cannot update immediately, block com_cck at the WAF for guest traffic and treat the database password, any API keys in configuration.php and any credentials stored in files above the web root as disclosed - rotate them.

Affected versions: < 3.30.0
