{"schema":"threatline.record/2","record":{"id":"CVE-2026-57486","aliases":["GHSA-q54q-vx78-v9rq"],"summary":"pupnp: NULL pointer dereference in ixmlNode_compare crashes on non-namespaced attributes","details":"pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, ixmlNode_compare in ixml/src/node.c passes the nullable nodeValue, namespaceURI, prefix, and localName fields directly to strcmp. Non-namespaced attributes created by ixmlDocument_createAttribute legitimately leave those fields NULL. When ixmlElement_removeAttributeNode compares two distinct attribute objects with the same nodeName through find_condition_node, the pointer-identity shortcut does not apply and the comparison dereferences NULL, causing a process crash when application handling of attacker-controlled XML reaches this path. 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-2026-57486","source_modified_at":"2026-10-16T15:56:47.362Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"pupnp","vendor":"pupnp","versions":[{"version":"< 2.0.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00411,"percentile":0.34318,"score_date":"2026-10-23"},"published_at":"2026-10-16T15:32:57.234Z","modified_at":"2026-10-16T15:56:47.362Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-57486","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T15:56:47.362Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-57486","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-q54q-vx78-v9rq","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/pupnp/pupnp/commit/4b2f775e3b98de3cfb096707bcde040c5562d9ec","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":"yes","technical_impact":"partial","assessed_at":"2026-10-16T15:56:13.970808Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T15:56:47.362Z","content_hash":"33bb74249840ab8bfaeb54cd9c03f3a8aba652a29d468665c875d8bdae3dd4cd"}}
