CVE-2026-34938: Praison Praisonaiagents

Critical severity, CVSS 10.0. EPSS: 0.8% chance of exploitation in the next 30 days.

PraisonAI is a multi-agent teams system. Prior to version 1.5.90, execute_code() in praisonai-agents runs attacker-controlled Python inside a three-layer sandbox that can be fully bypassed by passing a str subclass with an overridden startswith() method to the _safe_getattr wrapper, achieving arbitrary OS command execution on the host. This issue has been patched in version 1.5.90.

Affected products

• Praison Praisonaiagents: before 1.5.90 (fixed in 1.5.90)
