CVE-2026-57125: Mervinpraison Praisonai

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.59 and praisonaiagents 1.6.59, the unauthenticated POST /api/v1/runs Jobs API accepts attacker-controlled agent_yaml, and the approve field can mark execute_command as YAML-approved before @require_approval checks critical tools. This chain allows a remote caller to cause a configured language model agent to invoke arbitrary operating-system commands without credentials or operator interaction. This vulnerability is fixed in praisonai 4.6.59 and praisonaiagents 1.6.59 as fixed versions.

Affected products

• Mervinpraison Praisonai: before 4.6.59 (fixed in 4.6.59)
• Mervinpraison Praisonaiagents: before 1.6.59 (fixed in 1.6.59)
