CVE-2026-62240 is a server-side request forgery vulnerability in crewAIInc's crewAI product affecting versions before 1.15.1. The issue lies in the validate_url function, which attempts to prevent SSRF by performing a one-shot DNS resolution and blocklist check but ultimately returns the original URL unchanged. This flaw enables attackers to circumvent these checks by supplying URLs that redirect to internal network addresses or leverage DNS rebinding techniques, potentially allowing unauthorized access to internal services and cloud metadata endpoints. The vulnerability is rated high severity with a CVSS 4.0 score of 8.3. There is no vendor advisory or patch information available at this time, and the product is not a cloud service, so remediation depends on vendor updates.

Successful exploitation could allow an unauthenticated attacker to perform SSRF attacks against internal network resources and cloud metadata endpoints by bypassing the URL validation mechanism. This could lead to unauthorized information disclosure or interaction with internal services that are otherwise inaccessible externally. The vulnerability does not require privileges or user interaction beyond supplying a crafted URL.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, users should monitor for vendor updates and consider implementing additional network-level protections or URL validation controls to mitigate SSRF risks until a patch is available.
