CVE-2026-41682 Details
Description
pupnp is an SDK for development of UPnP device and control point applications. Prior to version 1.18.5, pupnp is vulnerable to SRRF port confusion due to port truncation via atoi() cast in parse_uri(). This issue has been patched in version 1.18.5.
A port confusion vulnerability allowing Server-Side Request Forgery (SSRF) via port redirection has been identified in pupnp versions prior to 1.18.5. The issue arises from improper port validation in the 'parse_uri()' function, where the 'atoi()' function truncates out-of-range port values. This flaw can be exploited by a rogue UPnP device to redirect connections to arbitrary internal ports, potentially bypassing port-based access controls and allowing service fingerprinting.
Users should upgrade to pupnp version 1.18.5, where this vulnerability has been patched.
