The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

symfony/http-foundation is a set of reusable PHP components.
Affected versions of this package are vulnerable to Access Restriction Bypass. It maintained support for (legacy) IIS headers (X-Original-URL
or X-Rewrite-URL
) that allowed users to override the path in a request URL.
As a result, it allowed a user to access one URL but have Symfony return a different one which can bypass restrictions on higher level caches and web servers.
