CVE-2026-71240 (GCVE-0-2026-71240)

Vulnerability from cvelistv5 – Published: 2026-08-05 10:56 – Updated: 2026-08-10 11:45

Title

DjangoCRM - Unauthenticated Open Redirect via toggle_default_sorting next_url Parameter

Summary

DjangoCRM's toggle_default_sorting view is the only route in common/urls.py that is not wrapped in login_required or staff_member_required, and it 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 (blocking only cross-domain redirects) while allowing any same-site path with no authentication required to reach the view.

Severity

4.3 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
