Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

PraisonAI versions before 4.6.58 are vulnerable to server-side request forgery through the webhook_url field in the Jobs API. The validator accepts a URL when DNS resolution fails and does not re-check the address before the server sends its request, so an attacker can use DNS rebinding to direct the request to internal hosts. Upgrade to PraisonAI 4.6.58 or later.
