{"cve":"CVE-2026-56838","nvd":{"published":"2026-10-23T12:18:15.357","modified":"2026-10-23T12:18:15.473","status":"Deferred","description":"PraisonAI is a multi-agent teams system. From version 4.5.87 to before version 4.6.59, PraisonAI recipe execution blocks default-denied dangerous tools unless the caller explicitly passes allow_dangerous_tools=True. The normal recipe.run() path enforces this with _check_tool_policy(). The streaming path, recipe.run_stream(), loads the same recipe, checks dependencies, and then calls _execute_recipe() without running the dangerous-tool policy check. As a result, a recipe that honestly declares execute_command in TEMPLATE.yaml requires.tools is denied by recipe.run(), but reaches the execution engine through recipe.run_stream() with allow_dangerous_tools=False. This issue has been patched in version 4.6.59.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-78","CWE-693","CWE-863"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-v847-hxxw-3pxg"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-56838","score":0.00146,"percentile":0.03816,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v847-hxxw-3pxg","url":"https://osv.dev/vulnerability/GHSA-v847-hxxw-3pxg","summary":"PraisonAI recipe.run_stream skips dangerous-tool policy enforcement","modified":"2026-07-23T15:11:26.264669943Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":[">=4.5.87 <4.6.59"],"fixed":["4.6.59"]}]},{"id":"PYSEC-2026-3520","url":"https://osv.dev/vulnerability/PYSEC-2026-3520","summary":"PraisonAI recipe.run_stream skips dangerous-tool policy enforcement","modified":"2026-07-23T15:00:20.940946166Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":[">=4.5.87 <4.6.59"],"fixed":["4.6.59"]}]}],"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).
