Attackers can create a session via POST /sessions and post a message via POST /sessions/{id}/messages without credentials, causing the Deep Agents ReAct loop to run attacker-directed shell commands through the local shell backend, resulting in remote code execution as the server process.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-306","CWE-1188"],"vendors":[],"products":[],"references":[{"url":"https://github.com/CognicellAI/Cognition/releases/tag/v0.13.0","tags":[]},{"url":"https://www.lasso.security/vulnerability-database/cve-2026-109437","tags":[]},{"url":"https://www.vulncheck.com/advisories/cognition-unauthenticated-rce-via-local-shell-backend","tags":[]}],"exploitRefs":[{"url":"https://github.com/CognicellAI/Cognition/releases/tag/v0.13.0","tags":[]}],"hasPoc":true,"ai":null}
