Puma PROXY Protocol v1 Parser Allows Remote Memory Exhaustion

Impact PROXY protocol support for Puma was added in version 5.5.0. When PROXY protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer. It waits for "\r\n" to determine whether a PROXY v1 line is present. If an attacker opens a TCP connection and continuously sends bytes...

Pydantic AI: SSRF cloud-metadata blocklist bypass via IPv4-mapped IPv6 (Incomplete fix of CVE-2026-25580)

Summary When an application using Pydantic AI opts a URL into forcedownload='allow-local' which disables the default block on private/internal IPs, the cloud-metadata blocklist could be bypassed by encoding the metadata IP in an IPv6 transition form IPv4-mapped IPv6, 6to4, or NAT64. Dual-stack an...
