{"id":"CVE-2026-26445","details":"stomper 5e2741e is vulnerable to Denial of Service. A malicious client can send partial STOMP frames and keep the TCP connections open, which, combined with the broker s use of edge-triggered epoll (EPOLLET) and MSG_PEEK in recv(), causes sockets to enter a permanent half-read state. When enough such connections accumulate, the broker stops receiving any further epoll events for those sockets and eventually hangs in epoll_wait, effectively refusing to process new messages.","modified":"2026-10-28T02:31:03.193914303Z","published":"2026-08-26T00:00:00Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26445.json","cna_assigner":"mitre"},"references":[{"type":"WEB","url":"https://github.com/songxpu/bug_report/blob/master/Stomp/stomper_vuln5.md"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26445.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26445"},{"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-2026-26445.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:N/I:N/A:H"}]}
