CVE-2026-27461: Pimcore vulnerable to SQL injection via unsanitized filter value in Dependency Dao RLIKE clause

The filter query parameter in the dependency listing endpoints is JSON-decoded and the value field is concatenated directly into RLIKE clauses without sanitization or parameterized queries.

Affected code in models/Dependency/Dao.php:

• getFilterRequiresByPath() lines 90, 95, 100
• getFilterRequiredByPath() lines 148, 153, 158

All 6 locations use direct string concatenation like:

“AND LOWER(CONCAT(o.path, o.key)) RLIKE ‘”.$value."’"

Note that $orderBy and $orderDirection in the same methods (lines 75-81) ARE properly whitelist-validated, but $value has zero sanitization.

Entry points (pimcore/admin-ui-classic-bundle ElementController.php):

• GET /admin/element/get-requires-dependencies (line 654)
• GET /admin/element/get-required-by-dependencies (line 714)

The controller JSON-decodes the filter query param and passes $filter[‘value’] straight to the Dao without any escaping.
