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 job webhook URL. The webhook validator accepts a URL when DNS resolution fails, and the webhook is later sent using a fresh DNS lookup, so an attacker who can submit jobs to the Jobs API could redirect webhook posts to internal private addresses. Upgrade to PraisonAI 4.6.58 or later.
