{"cve":"CVE-2026-44336","nvd":{"published":"2026-05-08T14:16:46.437","modified":"2026-06-17T10:50:31.370","status":"Modified","description":"PraisonAI is a multi-agent teams system. Prior to version 4.6.34, PraisonAI's MCP (Model Context Protocol) server (praisonai mcp serve) registers four file-handling tools by default — praisonai.rules.create, praisonai.rules.show, praisonai.rules.delete, and praisonai.workflow.show. Each accepts a path or filename string from MCP tools/call arguments and joins it onto ~/.praison/rules/ (or, for workflow.show, accepts an absolute path) with no containment check. The JSON-RPC dispatcher passes params[\"arguments\"] blind to each handler via **kwargs without validating against the advertised input schema. By setting rule_name=\"../../<some-path>\" an attacker walks out of the rules directory and writes any file the running user can write. Dropping a Python .pth file into the user site-packages directory escalates this primitive to arbitrary code execution in any subsequent Python process the user spawns — the next praisonai CLI invocation, an IDE script run, the user's python REPL, or any background Python service. This issue has been patched in version 4.6.34.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-20","CWE-22","CWE-94","CWE-829","CWE-913"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-9mqq-jqxf-grvw","https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-9mqq-jqxf-grvw"],"products":["praison:praisonai"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-44336","score":0.0062,"percentile":0.49734,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9mqq-jqxf-grvw","url":"https://osv.dev/vulnerability/GHSA-9mqq-jqxf-grvw","summary":"PraisonAI MCP `tools/call` path-traversal => RCE via Python `.pth` injection","modified":"2026-06-29T12:26:09.260974068Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.6.34"],"fixed":["4.6.34"]}]},{"id":"PYSEC-2026-472","url":"https://osv.dev/vulnerability/PYSEC-2026-472","summary":"PraisonAI MCP `tools/call` path-traversal => RCE via Python `.pth` injection","modified":"2026-07-13T16:15:32.514107434Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.6.34"],"fixed":["4.6.34"]}]}],"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).
