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.","state":0,"publishedAt":"2026-10-19T18:22:57.431+00:00","modifiedAt":"2026-10-23T13:28:30.752+00:00","affected":[{"ecosystem":"Vendor product","name":"Cognition","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"CognicellAI\",\n                    \"product\": \"Cognition\",\n                    \"packageURL\": \"pkg:github/CognicellAI/Cognition\",\n                    \"repo\": \"https://github.com/CognicellAI/Cognition\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.13.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://www.lasso.security/vulnerability-database/cve-2026-109437","https://github.com/CognicellAI/Cognition/releases/tag/v0.13.0","https://www.vulncheck.com/advisories/cognition-unauthenticated-rce-via-local-shell-backend"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-109437","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-109437","identifiers":["CVE-2026-109437"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
