What is CVE-2026-57124?

PraisonAI, a multi-agent teams system, has a security flaw in its UI host applications before version 4.6.59. These applications expose a POST endpoint that does not require authentication, allowing unauthenticated clients to send commands and arguments. Due to this, if the system's handshake fails, an attacker could still execute commands using the UI service account. The vulnerability is addressed in the release of version 4.6.59.

Affected Version(s)

PraisonAI < 4.6.59
