{"cve":"CVE-2026-61592","nvd":{"published":"2026-09-16T22:17:02.900","modified":"2026-09-30T17:51:56.193","status":"Deferred","description":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, SSE sessions were keyed solely by a client-chosen `session_id` with no binding to the authenticated user — a control the WebSocket transport has but that was dropped on SSE. An attacker who learns (or a victim who leaks) a `session_id` could connect to the message endpoint and dispatch event handlers that execute with the victim's identity and state. This is fixed in djust 1.0.7. Each SSE session is bound to its owning principal at creation and cross-principal access is rejected; SSE session creation is additionally capped per principal. As a workaround, disable the SSE transport.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4},"cwes":["CWE-384","CWE-639","CWE-862"],"references":["https://github.com/djust-org/djust/releases/tag/v1.0.7","https://github.com/djust-org/djust/security/advisories/GHSA-f795-p5jw-j6g2"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-61592","score":0.00388,"percentile":0.32569,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f795-p5jw-j6g2","url":"https://osv.dev/vulnerability/GHSA-f795-p5jw-j6g2","summary":"djust: SSE sessions are not bound to the authenticated user; the client-chosen session_id is the sole authorization capability (session hijack)","modified":"2026-10-01T17:56:05.190087173Z","packages":[{"ecosystem":"PyPI","name":"djust","purl":"pkg:pypi/djust","ranges":["<1.0.7"],"fixed":["1.0.7"]}]},{"id":"PYSEC-2026-4043","url":"https://osv.dev/vulnerability/PYSEC-2026-4043","summary":"djust: SSE sessions are not bound to the authenticated user; the client-chosen session_id is the sole authorization capability (session hijack)","modified":"2026-10-01T17:45:02.053457927Z","packages":[{"ecosystem":"PyPI","name":"djust","purl":"pkg:pypi/djust","ranges":["<1.0.7"],"fixed":["1.0.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
