An attacker can open a TCP connection to the MOOSDB port and send no data, causing the accept thread to block indefinitely while holding the socket-list lock, preventing all subsequent client connections.","published":"2026-09-03T23:17:24.030","modified":"2026-09-03T23:17:24.030","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":{"url":"https://github.com/themoos/core-moos/commit/8d940303949a850d4625eca2a60f27adee9c3ec4","label":"themoos/core-moos@8d94030"},"references":[{"type":"WEB","url":"https://github.com/themoos/core-moos"},{"type":"WEB","url":"https://github.com/themoos/core-moos/blob/ec9c77c68fcbdef8f5e4c60fe243acd223433f0c/Core/libMOOS/Comms/MOOSCommServer.cpp#L922"},{"type":"WEB","url":"https://github.com/themoos/core-moos/commit/8d940303949a850d4625eca2a60f27adee9c3ec4"},{"type":"WEB","url":"https://github.com/themoos/core-moos/pull/83"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/moos-core-moos-through-10.4.0-moosdb-accept-loop-denial-of-service"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-03T23:17:24.030"}}
