CVE-2026-55535
PraisonAI vulnerable to Server-Side Request Forgery via DNS rebinding bypass in webhook_url validation
Impact
PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the Jobs API validate_webhook_url() path fails open on socket.gaierror and does not bind the validated address to the later request. An attacker webhook_url can later resolve to 127.0.0.1, 169.254.169.254, or another internal address. This issue is fixed in version 4.6.58.
