What is CVE-2025-64500?

A vulnerability in Symfony's HttpFoundation component affects versions prior to 5.4.50, 6.4.29, and 7.3.7. This flaw arises from the improper handling of the PATH_INFO variable in the Request class, which can generate URL paths that do not begin with a /. Consequently, this can facilitate unintended access control bypassing, as it undermines assumptions made in certain access rules tied to the URL path structure. The issue is rectified in subsequent releases where the Request class enforces that URL paths consistently start with a /.

Affected Version(s)

symfony >= 2.0.0, < 5.4.50 < 2.0.0, 5.4.50

symfony >= 6.0.0, < 6.4.29 < 6.0.0, 6.4.29

symfony >= 7.0.0, < 7.3.7 < 7.0.0, 7.3.7
