{"cve":"CVE-2026-40149","nvd":{"published":"2026-04-09T22:16:35.750","modified":"2026-10-26T21:10:00.170","status":"Analyzed","description":"PraisonAI is a multi-agent teams system. Prior to 4.5.128, the gateway's /api/approval/allow-list endpoint permits unauthenticated modification of the tool approval allowlist when no auth_token is configured (the default). By adding dangerous tool names (e.g., shell_exec, file_write) to the allowlist, an attacker can cause the ExecApprovalManager to auto-approve all future agent invocations of those tools, bypassing the human-in-the-loop safety mechanism that the approval system is specifically designed to enforce. This vulnerability is fixed in 4.5.128.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N","score":7.3},"cwes":["CWE-396"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-4wr3-f4p3-5wjh","https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-4wr3-f4p3-5wjh"],"products":["praison:praisonai"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-40149","score":0.00227,"percentile":0.13382,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-4wr3-f4p3-5wjh","url":"https://osv.dev/vulnerability/GHSA-4wr3-f4p3-5wjh","summary":"PraisonAI: Unauthenticated Allow-List Manipulation Bypasses Agent Tool Approval Safety Controls","modified":"2026-07-13T16:42:53.881868954Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.5.128"],"fixed":["4.5.128"]}]},{"id":"PYSEC-2026-2901","url":"https://osv.dev/vulnerability/PYSEC-2026-2901","summary":"PraisonAI: Unauthenticated Allow-List Manipulation Bypasses Agent Tool Approval Safety Controls","modified":"2026-07-13T16:33:01.609664140Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.5.128"],"fixed":["4.5.128"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
