CVE-2026-55535Public exploitNetwork attack vector

Authenticated SSRF via webhook DNS rebinding

Published Aug 25, 2026 · Updated Aug 25, 2026

Server-side request forgery in PraisonAI before 4.6.58 allows remote authenticated users to reach internal services via job webhooks. JobSubmitRequest.validate_webhook_url accepts DNS failures, while JobExecutor later resolves the unbound hostname again before posting results. Exploitation requires Jobs API access and attacker-controlled DNS; the resulting POST can alter internal-service data or disclose job results.
