CVE-2026-57488

pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, rawtoint in upnp/src/genlib/net/http/httpparser.c parses Content-Length with strtol and casts the resulting long to a 32-bit int before the caller stores it as unsigned int. On LP64 systems, values...

CVE-2026-77630

The pupnp SDK, used for UPnP device development, is vulnerable to a Denial of Service (DoS) attack in versions prior to 22.0.4 . The root cause is that the parse_hostport function in upnp/src/genlib/net/uri/uri.c synchronously calls getaddrinfo. This occurs when parse_uri processes attacker-suppl...

CVE-2026-57487

The pupnp SDK (prior to version 2.0.2 ) contains a vulnerability where chunked Transfer-Encoding in HTTP requests allows an attacker to bypass g_maxContentLength checks. The HTTP parser in upnp/src/genlib/net/http/httpparser.c fails to set the content_length correctly for chunked bodies, while pa...
