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.","published":"2026-08-26T20:17:11.400","modified":"2026-09-02T13:17:14.830","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/mdoi/stomper"},{"type":"WEB","url":"https://github.com/songxpu/bug_report/blob/master/Stomp/stomper_vuln5.md"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-02T13:17:14.830"}}
