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.","categories":["Unclassified"],"product":"Cognition","vendor":"CognicellAI","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109437","source_modified_at":"2026-10-23T13:28:30.752Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Cognition","vendor":"CognicellAI","versions":[{"status":"affected","version":"0","versionType":"semver","lessThan":"0.13.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109437","source_modified_at":"2026-10-23T13:28:30.752Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Cognition","ecosystem":null},"version":"0.13.0","basis":"first unaffected version stated in the CVE record"}],"cvss":9.2,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00608,"percentile":0.48476,"score_date":"2026-10-23"},"published_at":"2026-10-19T18:22:57.431Z","modified_at":"2026-10-23T13:28:30.752Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109437","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T13:28:30.752Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109437","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.lasso.security/vulnerability-database/cve-2026-109437","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://github.com/CognicellAI/Cognition/releases/tag/v0.13.0","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/cognition-unauthenticated-rce-via-local-shell-backend","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-20T16:03:09.450817Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T13:28:30.752Z","content_hash":"7261e3252152bfc1e6e541b6699e7f188e939e154019e041a92f349fc9b2a10d"}}
