CVE-2026-26445: n/a
Description
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.

Technical Analysis
The vulnerability in stomper 5e2741e arises from the handling of partial STOMP frames combined with the broker's use of edge-triggered epoll (EPOLLET) and MSG_PEEK in recv(). A malicious client can exploit this by sending partial frames that keep TCP connections open in a half-read state. When enough such connections accumulate, the broker stops receiving further epoll events for those sockets and hangs in epoll_wait, resulting in a denial of service condition where new messages cannot be processed.
Potential Impact
This vulnerability results in a denial of service (DoS) condition affecting the availability of the stomper broker. Attackers can cause the broker to hang and stop processing new messages by exhausting its ability to handle TCP connections properly. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround is currently documented. Users should monitor vendor communications for updates and consider limiting exposure to untrusted clients until a fix is available.
