CVE-2026-41682 May 08, 22:47 MEDIUM PATCH This Month

Port confusion in pupnp's URI parser allows remote unauthenticated attackers to bypass port-based access controls by supplying port values exceeding 65535 in crafted URIs. The integer truncation caused by atoi() in parse_hostport() within uri.c causes the parsed port to wrap around (e.g., port 65537 resolves to port 1), enabling SSRF-style redirection to unintended internal services. All pupnp releases prior to 1.18.5 are affected; no confirmed active exploitation exists (EPSS 0.04%, no KEV listing), but SSVC rates the attack as automatable with partial technical impact.
