Machine-written summary

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

The crewai-tools package versions before 1.15.1 are vulnerable to server-side request forgery in its URL validation function, which checks DNS resolution and blocklists only once and then returns the original URL unchanged. An attacker who can supply URLs to the tool can use redirects or DNS rebinding to reach internal services and cloud metadata endpoints. Upgrade crewai-tools to version 1.15.1 or later.
