In SyliusResourceBundle before versions 1.3.14, 1.4.7, 1.5.2 and 1.6.4, request parameters injected inside an expression evaluated by symfony/expression-language package havent been sanitized properly. This allows the attacker to access any public service by manipulating that request parameter, allowing for Remote Code Execution. This issue has been patched for versions 1.3.14, 1.4.7, 1.5.2 and 1.6.4. Versions prior to 1.3 were not patched.

Weakness

The product constructs all or part of an expression language (EL) statement in a framework such as a Java Server Page (JSP) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended EL statement before it is executed.
