Upgrade symphony/symphony
to version 4.4.0, 4.4.13, 5.1.0, 5.1.5 or higher.
Overview
symphony/symphony is a PHP framework for web applications and a set of reusable PHP components.
Affected versions of this package are vulnerable to Remote Code Execution (RCE). The CachingHttpClient
class from the HttpClient
Symfony component relies on the HttpCache
class to handle requests. HttpCache
uses internal headers like X-Body-Eval
and X-Body-File
to control the restoration of cached responses. The class was initially written with surrogate caching and ESI support in mind (all HTTP calls come from a trusted backend in that scenario). But when used by CachingHttpClient
and if an attacker can control the response for a request being made by the CachingHttpClient
, remote code execution is possible.
