symfony: Symfony is a PHP framework for web and console applications and a set of reusable PHP components
CVE-2026-48784 is fixed in symfony on 1 platform, first by DEBIAN-CVE-2026-48784, released June 24, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.53, 6.4.41, 7.4.13, and 8.0.13, UrlGenerator::doGenerate() used strtr() dot-segment encoding that skipped every other chained ../ or ./ segment, allowing attacker-controlled route parameters to generate URLs that collapse to a different path under RFC 3986 normalization. This issue is fixed in versions 5.4.53, 6.4.41, 7.4.13, and 8.0.13.
