Summary

CrewAI before 1.15.17 contains a server-side request forgery flaw (CWE-918). Its SSRF guard and HTTP client each check the opposite content passed to them, so malicious content in URLs goes unchecked. An unauthenticated remote attacker who injects a malicious URL, for example through ScrapWebsiteTool, can make the server send requests to destinations of their choice, with high confidentiality and integrity impact.

Description from the CNA

CrewAI contains an SSRF vulnerability caused by its SSRF guard and HTTP client, which both miss malicious content in URLs by checking opposite content passed to it, enabling any request that injects a malicious URL to perform SSRF, such as with the ScrapWebsiteTool.
