Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Symfony's HttpFoundation component defines an object-oriented layer for the HTTP specification. Starting in version 2.0.0 and prior to version 5.4.50, 6.4.29, and 7.3.7, the Request class improperly interprets some PATH_INFO in a way that leads to representing some URLs with a path that doesn't start with a /. This can allow bypassing some access control rules that are built with this /-prefix assumption. Starting in versions 5.4.50, 6.4.29, and 7.3.7, the Request class now ensures that URL paths always start with a /.
CVE-2025-64500
This high-severity CVE scores 7.3 under NVD CVSS v3. EPSS exploit probability: 6.3%, top 9% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
