Before version 1.0.7, a lack of origin verification on the SSE stream endpoint, combined with @csrf_exempt decorators on message POST endpoints, allowed an attacker to hijack active client sessions through cross-origin interactions.\n\n## TL;DR\nA validation omission in djust allows attackers to hijack reactive user sessions via cross-site requests, mounting unauthorized server-side components and executing state-changing handlers.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-352: Cross-Site Request Forgery (CSRF)\n- **Attack Vector**: Network\n- **CVSS v3.1 Score**: 8.1\n- **Impact**: High (Confidentiality, Integrity)\n- **Exploit Status**: poc\n- **KEV Status**: Not Listed\n\n## Affected Systems\n\n- Applications utilizing the djust framework for Django reactive server-side rendering\n- **djust**: < 1.0.7 (Fixed in: `1.0.7`)\n\n## Mitigation\n\n- Upgrade the djust Python package to version 1.0.7 or later.\n- Implement Origin header validation in intermediate reverse proxies.\n- Reject non-JSON Content-Type values on POST requests targeting SSE message endpoints.\n\n**Remediation Steps:**\n1. Update your requirements.txt or Pipfile to specify djust>=1.0.7.\n2. Re-deploy the application to apply the package update.\n3. Verify the fix by attempting a cross-origin connection using an unauthorized Origin header.\n\n## References\n\n- [GitHub Security Advisory GHSA-pg97-jvmf-qfvc](https://github.com/djust-org/djust/security/advisories/GHSA-pg97-jvmf-qfvc)\n- [djust v1.0.7 Release](https://github.com/djust-org/djust/releases/tag/v1.0.7)\n- [CVE Record](https://www.cve.org/CVERecord?id=CVE-2026-61593)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-61593) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-09-16T16:32:19.994252Z"}, {"uuid": "f2b33cbc-3037-49d3-a7e0-3edc898903dd", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-61593", "type": "seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/22eovhmpbg6st", "content": "CVE-2026-61593 - djust has Cross-Site Request Forgery on the Server-Sent-Events transport: a cross-origin page can drive a victim-authenticated SSE session\nCVE ID : CVE-2026-61593\n \n Published : Sept. 16, 2026, 4:17 p.m. | 30\u00a0minutes ago\n \n Description : djust provides Phoenix...", "creation_timestamp": "2026-09-16T17:26:31.838289Z"}]}
