{"id":"CVE-2026-26448","details":"Stomper 5e2741e is vulnerable to Use-After-Free. When a client sends multiple CONNECT frames on the same TCP connection, and subsequently another client (or a later connection) sends SEND frames to a destination previously subscribed on that connection, the broker may dereference a pointer to a StompStreamSocket object that has already been freed. This results in a heap use-after-free and process crash. Because the protocol does not authenticate or restrict such sequences by default.","modified":"2026-10-28T02:31:13.925345153Z","published":"2026-08-26T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26448.json"},"references":[{"type":"WEB","url":"https://github.com/songxpu/bug_report/blob/master/Stomp/stomper_vuln4.md"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26448.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26448"},{"type":"PACKAGE","url":"https://github.com/mdoi/stomper"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mdoi/stomper","events":[{"introduced":"0"},{"last_affected":"5e2741e"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"last_affected":"5e2741e"}],"source":"DESCRIPTION"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-26448.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
