Symfony: SQL Injection in PdoAdapter::doClear() via Unsanitized $prefix

Summary

CVE	CVE-2026-45073
State	PUBLISHED
Assigner	GitHub_M
Source Priority	CVE Program / NVD first with legacy fallback

Description	Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, PdoAdapter::doClear() builds a DELETE statement using a namespace derived from the caller-supplied $prefix without binding or escaping it, allowing a caller able to influence $prefix to break out of the LIKE literal and alter query semantics or deletion scope. This issue is fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12.
