CVE-2026-34936: Praison Praisonai

High severity, CVSS 7.7. EPSS: 0.4% chance of exploitation in the next 30 days.

PraisonAI is a multi-agent teams system. Prior to version 4.5.90, passthrough() and apassthrough() in praisonai accept a caller-controlled api_base parameter that is concatenated with endpoint and passed directly to httpx.Client.request() when the litellm primary path raises AttributeError. No URL scheme validation, private IP filtering, or domain allowlist is applied, allowing requests to any host reachable from the server. This issue has been patched in version 4.5.90.

Affected products

• Praison Praisonai: before 4.5.90 (fixed in 4.5.90)
