{"schema":"threatline.record/2","record":{"id":"CVE-2026-57488","aliases":["GHSA-g6c2-x4r9-352g"],"summary":"pupnp: Integer truncation in HTTP Content-Length parsing enables request smuggling","details":"pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, raw_to_int 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 greater than INT_MAX can truncate or wrap, so the HTTP parser can accept a body length different from the declared value. A remote adjacent-network peer can use the resulting parser disagreement to leave bytes to be interpreted as another request in persistent or proxied contexts, or can make a worker wait for an extremely large body and cause denial of service. This issue is fixed in 2.0.2.","categories":["Unclassified"],"product":"pupnp","vendor":"pupnp","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-57488","source_modified_at":"2026-10-16T19:08:25.462Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"pupnp","vendor":"pupnp","versions":[{"version":"< 2.0.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00335,"percentile":0.25719,"score_date":"2026-10-23"},"published_at":"2026-10-16T15:34:49.625Z","modified_at":"2026-10-16T19:08:25.462Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-57488","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T19:08:25.462Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-57488","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-g6c2-x4r9-352g","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/pupnp/pupnp/commit/de9602aef34ff722f3630d66c9be8eaa0aa9f012","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/pupnp/pupnp/releases/tag/release-2.0.2","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-16T19:08:06.620494Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T19:08:25.462Z","content_hash":"29fc8beb4c784dc0514d44c565b96f7385826cdf191ebe33951b8ddc5299ea72"}}
