Prior to 22.0.4, parse_hostport in upnp/src/genlib/net/uri/uri.c synchronously calls getaddrinfo while parse_uri is processing attacker-supplied hostnames from inbound HTTP request targets in upnp/src/genlib/net/http/httpparser.c and GENA SUBSCRIBE CALLBACK headers handled by create_url_list in upnp/src/gena/gena_device.c. A remote unauthenticated peer can choose a slow or nonresponsive hostname and block a bounded miniserver worker for the resolver timeout, allowing a small number of requests to exhaust the thread pool and deny UPnP service. This issue is fixed in 22.0.4."}], "lastModified": "2026-10-20T19:36:35.460", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:pupnp_project:pupnp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "64F55492-160E-4563-BBB1-6EB1A23465DA", "versionEndExcluding": "22.0.4"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
