CVE-2026-57133: Mervinpraison Praisonai

High severity, CVSS 8.8. EPSS: 0.8% chance of exploitation in the next 30 days.

PraisonAI is a multi-agent teams system. From 1.5.1 until 1.7.2, the shell() helper exported from src/praisonai-ts/src/tools/utility-tools.ts checks only the first whitespace-delimited token against safeCommands and then passes the complete original string to child_process.exec(). A string that starts with an allowed read-only command can append a second non-allowlisted command through shell syntax, allowing arbitrary command execution with the PraisonAI process privileges. This issue is fixed in version 1.7.2.

Affected products

• Mervinpraison Praisonai: from 1.5.1, before 1.7.2 (fixed in 1.7.2)
