now ensure that 403s are returned whether the user exists or not if the password is invalid or if the user does not exist.\n\nThe patch for this issue is available

"summary": "RCE in Symfony\nDescription\n-----------\n\nThe `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.\n\nResolution\n----------\n\nHTTP headers designed for internal use in `HttpCache` are now stripped from remote responses before being passed to `HttpCache`.\n\nThe patch for this issue is available [here](https://github.com/symfony/symfony/commit/d9910e0b33a2e0f993abff41c6fbc86951b66d78) for the 4.4 branch.\n\nCredits\n-------\n\nI would like to thank Matthias Pigulla (webfactory GmbH) for reporting and fixing the issue.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2020-15094", "reference_id": "", "reference_type": "", "scores": [ { "value":
