Prior to 4.6.59, the default UI host applications expose POST /api/mcp/connect without mandatory authentication and accept caller-controlled command and args values that PraisonAIUI passes to StdioMCPClient to start a local process. Because the UI commands bind to 0.0.0.0 by default, a reachable unauthenticated client can execute commands as the UI service account even when the MCP handshake later fails. This vulnerability is fixed in 4.6.59.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-78","CWE-306"],"references":["https://github.com/MervinPraison/PraisonAI/commit/2adfe7e8323f6deec66925cf15a885b6238895e9","https://github.com/MervinPraison/PraisonAI/releases/tag/v4.6.59","https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-p75f-6fp4-p57w","https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-p75f-6fp4-p57w"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-57124","score":0.01035,"percentile":0.63897,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p75f-6fp4-p57w","url":"https://osv.dev/vulnerability/GHSA-p75f-6fp4-p57w","summary":"PraisonAI: Missing Authentication for Critical Function and Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in praisonai","modified":"2026-07-23T15:11:16.936627435Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.6.59"],"fixed":["4.6.59"]}]},{"id":"PYSEC-2026-3517","url":"https://osv.dev/vulnerability/PYSEC-2026-3517","summary":"PraisonAI: Missing Authentication for Critical Function and Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in praisonai","modified":"2026-07-23T15:00:22.210183505Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<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).
