CVE-2026-55535: Mervinpraison Praisonai

Medium severity, CVSS 6.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
