{"id":"CVE-2026-57486","published":"2026-10-16T16:18:44.510","lastModified":"2026-10-16T18:09:59.750","description":"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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-476"],"vendors":[],"products":[],"references":[{"url":"https://github.com/pupnp/pupnp/commit/4b2f775e3b98de3cfb096707bcde040c5562d9ec","tags":[]},{"url":"https://github.com/pupnp/pupnp/releases/tag/release-2.0.2","tags":[]},{"url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-q54q-vx78-v9rq","tags":[]},{"url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-q54q-vx78-v9rq","tags":[]}],"exploitRefs":[{"url":"https://github.com/pupnp/pupnp/commit/4b2f775e3b98de3cfb096707bcde040c5562d9ec","tags":[]},{"url":"https://github.com/pupnp/pupnp/releases/tag/release-2.0.2","tags":[]},{"url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-q54q-vx78-v9rq","tags":[]},{"url":"https://github.com/pupnp/pupnp/security/advisories/GHSA-q54q-vx78-v9rq","tags":[]}],"hasPoc":true,"ai":null}
