CVE-2026-74254Network attack vector

Data read and write via style ID injection

Published Aug 17, 2026 · Updated Aug 18, 2026

SQL injection in the styles model in Joomlack Page Builder CK before 3.6.5 allows attackers to read and modify database data. Public detail identifies the vulnerable locus as saved-style loading: style identifiers were used in database queries without escaping or numeric conversion, and the 3.6.4 fix sanitized the frontend path but left the administrator path using raw values. The Joomla CNA scores the issue as network-reachable with no privileges or user interaction, while the researcher notes the frontend vector was fixed in 3.6.4 and the backend path was only fully closed in 3.6.5.
