CyberRota Analysis
AI-GeneratedThe Symfony PHP framework versions 5.4.0 to 5.4.53, 6.4.41, 7.4.13, and 8.0.13 are vulnerable due to the omission of certain IPv6 transition prefixes in the NoPrivateNetworkHttpClient and IpUtils::PRIVATE_SUBNETS, which allows attackers to exploit URLs that should be blocked as private IPv4 targets. This vulnerability poses a high risk, enabling potential unauthorized access to private networks. Organizations using affected Symfony versions should prioritize updating to the patched versions to mitigate the risk of exploitation.

Original NVD Description
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 5.4.0 to 5.4.53, 6.4.41, 7.4.13, and 8.0.13, NoPrivateNetworkHttpClient and IpUtils::PRIVATE_SUBNETS omitted IPv6 transition prefixes such as 6to4, NAT64, Teredo, and IPv4-compatible IPv6, allowing attacker-supplied URLs to represent private IPv4 targets in forms that IpUtils::isPrivateIp() did not block. This issue is fixed in versions 5.4.53, 6.4.41, 7.4.13, and 8.0.13.
