In SyliusResourceBundle before versions 1.3.14, 1.4.7, 1.5.2 and 1.6.4, rrequest parameters injected inside an expression evaluated by `symfony/expression-language` package haven't been sanitized properly. This allows the attacker to access any public service by manipulating that request parameter, allowing for Remote Code Execution.
