This affects the function launch_goal of the file im_client/communication/communication_layer.py of the component Collaboration Layer. Performing a manipulation of the argument max_turns results in infinite loop. The attack may be initiated remotely. The exploit is now public and may be used. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.","score":5.3,"severity":"medium","published":"2026-11-07T12:45:20.360Z","modified":"2026-11-10T20:23:56.274Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"OpenBMB","name":"Internet of Agents","platforms":[],"versions":[{"version":"9d78e88e47160eb42ee1ee8538c05e1c2c47877a","status":"affected"}],"cpes":["cpe:2.3:a:openbmb:internet_of_agents:*:*:*:*:*:*:*:*"],"source":"VulDB","url":"https://www.cve.org/CVERecord?id=CVE-2026-123964"}],"remediation":[],"references":["https://vuldb.com/vuln/432034","https://vuldb.com/vuln/432034/cti","https://vuldb.com/cve/CVE-2026-123964","https://vuldb.com/submit/1033798","https://github.com/OpenBMB/IoA/issues/22"],"sources":[{"name":"CVE","id":"CVE-2026-123964","modified":"2026-11-10T20:23:56.274Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-123964"}],"assessments":[{"source":"VulDB","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","score":5.3},{"source":"VulDB","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:P/RL:X/RC:C","score":4.3},{"source":"VulDB","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:P/RL:X/RC:C","score":4.3},{"source":"VulDB","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:P/E:POC/RL:ND/RC:C","score":4}],"sourceAffected":[],"observedAt":"2026-11-10T21:15:12.831Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T03:00:33.317Z"},"coverage":[{"source":"NVD","status":"no-result","checkedAt":"2026-11-07T12:55:35.408Z","attemptedAt":"2026-11-07T12:55:35.408Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-11-07T12:55:35.635Z","attemptedAt":"2026-11-07T12:55:35.635Z"},{"source":"EUVD","status":"no-result","checkedAt":"2026-11-07T12:55:36.024Z","attemptedAt":"2026-11-07T12:55:36.024Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-07T12:55:35.860Z","attemptedAt":"2026-11-07T12:55:35.860Z"}],"evidence":[],"aiSummary":{"text":"OpenBMB Internet of Agents up to version 9d78e88e47160eb42ee1ee8538c05e1c2c47877a has an infinite loop vulnerability in the launch_goal function of communication_layer.py.
