Page Builder CK (com_pagebuilderck) 3.6.4 - SQL Injection in the styles model, backend vector still open
Page Builder CK 3.6.4 is still affected by CVE-2026-74254, the SQL injection in the styles handling, because that release only fixed half of it. The CNA records the whole issue as affecting versions 1.0.0 to 3.6.4 and scores it CVSS 4.0 9.3 Critical: 3.6.4 fixed the front-end vector, and 3.6.5 fixed the administrator one. On 3.6.4 specifically the remaining route is the administrator path, where the sanitising call discarded its own return value so the uncast style identifiers still reached the query, and reaching it needs an authenticated account with content editing rights on the component plus a valid session token. That is why this rule is scored lower than the 3.6.3 rule even though both carry the same CVE. Update to 3.6.5 or later, which applies the sanitising properly. Until you can update, restrict edit permissions on com_pagebuilderck to trusted users only.
