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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-57124)\n\nAffected packages:\n\n- `praisonai < 4.6.59`\n\nPatched in:\n\n- `praisonai 4.6.59`\n\nSource: https://osv.dev/vulnerability/GHSA-p75f-6fp4-p57w","depth":"abyssal","depthScore":66,"depthScoreParts":{"impact":53.9,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":203276,"id":"CVE-2026-57124","ts":1789416902197,"field":"exploit_available","old":"false","new":"true"}]}
