{"id":"CVE-2026-57136","aliases":["GHSA-vjv9-7m7j-h833"],"url":"https://o3.security/vulnerability/CVE-2026-57136","summary":"PraisonAI SandboxExecutor allowedCommands bypass via shell chaining","details":"PraisonAI is a multi-agent teams system. From 1.2.3 until 1.7.2, CommandValidator in src/praisonai-ts/src/cli/features/sandbox-executor.ts validates only the first whitespace-delimited executable against allowedCommands, then SandboxExecutor passes the complete command string to sh -c. A command beginning with an allowed executable can append a non-allowlisted command through shell metacharacters, causing arbitrary commands to run with the PraisonAI process privileges. This issue is fixed in version 1.7.2.","published":"2026-09-15T10:21:29.574Z","modified":"2026-09-16T03:47:09.773292581Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"praisonai","fixedVersion":"1.7.2"}],"fix":{"url":"https://github.com/MervinPraison/PraisonAI/commit/709a0387853709a5e2f2c34680fa64cada252c27","label":"MervinPraison/PraisonAI@709a038"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57136.json"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/709a0387853709a5e2f2c34680fa64cada252c27"},{"type":"WEB","url":"https://github.com/MervinPraison/PraisonAI/releases/tag/v4.6.60"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-vjv9-7m7j-h833"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57136"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T03:47:09.773292581Z"}}
