Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Saleor, 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

In Mirumee Saleor 2.7.0 (fixed in 2.8.0), CSRF protection middleware was accidentally disabled, which allowed attackers to send a POST request without a valid CSRF token and be accepted by the server.
