How to Fix CVE-2026-62240

To remediate this vulnerability, upgrade all affected Crewai tools dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

crewai-tools fixed: 1.15.1 
pip install crewai-tools>=1.15.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show crewai-tools

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-62240, inspect your installed packages using pip:

pip show crewai-tools

Analyze the terminal output to locate any version of Crewai tools in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.15.1), your application is affected.

Note: The pip show crewai-tools command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Crewai tools, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

CrewAI before 1.15.1 contains a server-side request forgery vulnerability in the validate_url function that performs one-shot DNS resolution and blocklist checks before returning the original URL unchanged. Attackers can bypass the security filter by supplying URLs that redirect to internal addresses or use DNS rebinding techniques to access internal services and cloud metadata endpoints.
