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.","state":0,"publishedAt":"2026-10-16T15:32:57.234+00:00","modifiedAt":"2026-10-16T15:56:47.362+00:00","affected":[{"ecosystem":"Vendor product","name":"pupnp","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"pupnp\",\n                    \"product\": \"pupnp\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.0.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/pupnp/pupnp/security/advisories/GHSA-q54q-vx78-v9rq","https://github.com/pupnp/pupnp/commit/4b2f775e3b98de3cfb096707bcde040c5562d9ec","https://github.com/pupnp/pupnp/releases/tag/release-2.0.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-57486","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57486","identifiers":["CVE-2026-57486"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
