CVE-2026-71240 DjangoCRM CVE debrief

Unauthenticated phishing redirects and referrer-based token leakage are possible due to insecure redirect handling in DjangoCRM's toggle_default_sorting view. This view does not require authentication or staff member privileges, allowing unauthenticated users to perform phishing redirects and potentially leak tokens via redirect chains. The insecure redirect handling is caused by the view's use of secure_url(next_url), which only verifies that the target host matches the current site's domain, without requiring any authentication for the redirect. As a result, attackers can exploit this vulnerability to redirect users to malicious sites, potentially leading to phishing attacks and token leakage. Affected product deployments should be reviewed for potential exposure, and defenders should verify the view's authentication and authorization settings to prevent such attacks.

Who should care

DjangoCRM users and administrators should review and update their installations to prevent potential phishing and token leakage risks. Affected operators, platforms, and security teams should assess their exposure and implement additional security measures as needed. Vulnerability management and security teams should prioritize this issue due to the potential for phishing redirects and token leakage.

Technical summary

The toggle_default_sorting view in DjangoCRM does not require authentication or staff member privileges, allowing unauthenticated users to perform phishing redirects and potentially leak tokens via redirect chains. This view redirects to a caller-supplied next_url GET parameter after only checking secure_url(next_url), which merely verifies the target host matches the current site's domain. Affected product context indicates that DjangoCRM users and administrators should review and update their installations to prevent potential phishing and token leakage risks.

Defensive priority

Medium priority due to potential phishing and token leakage risks.

Recommended defensive actions

  • Review and update the toggle_default_sorting view to enforce proper authentication and authorization.
  • Implement additional security measures to prevent phishing redirects and token leakage.
  • Monitor for potential exploitation attempts and update incident response plans accordingly.
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review.
