{"id":"PYSEC-2026-4039","summary":"djust's observability endpoints are network-exposed: the localhost gate is an opt-in middleware the docs omit, and the views enforce only DEBUG","details":"### Impact\ndjust's observability endpoints expose live view/session state and a remote method-invocation surface (`eval_handler`). The localhost restriction was an **opt-in middleware that the documented setup omits**; the views themselves enforced only `DEBUG`. In the misconfigured-but-documented scenario (DEBUG on, middleware not installed) a non-localhost client could read live application state and invoke handlers remotely.\n\n### Patches\nFixed in **djust 1.0.7**. The localhost restriction is enforced **in-view** on every observability endpoint (no longer dependent on a separately-installed middleware), and `eval_handler` is restricted; gated requests receive a non-disclosing response.\n\n### Workarounds\nEnsure `DEBUG=False` in production, and do not expose the observability endpoints to untrusted networks.","aliases":["CVE-2026-61590","GHSA-8g2f-g3gq-5rjv"],"modified":"2026-10-01T17:45:03.785225554Z","published":"2026-10-01T16:38:30.820008Z","references":[{"type":"WEB","url":"https://github.com/djust-org/djust/security/advisories/GHSA-8g2f-g3gq-5rjv"},{"type":"PACKAGE","url":"https://github.com/djust-org/djust"},{"type":"WEB","url":"https://github.com/djust-org/djust/releases/tag/v1.0.7"},{"type":"PACKAGE","url":"https://pypi.org/project/djust"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-8g2f-g3gq-5rjv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61590"}],"affected":[{"package":{"name":"djust","ecosystem":"PyPI","purl":"pkg:pypi/djust"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.7"}]}],"versions":["0.1.0","0.1.2","0.1.3","0.1.4","0.1.5","0.1.6","0.1.7","0.1.8","0.1.9","0.2.0","0.2.1","0.2.2","0.3.0","0.3.1","0.3.2","0.3.4","0.3.5","0.3.6","0.3.7","0.3.8","0.4.0","0.4.1","0.4.2","0.4.3","0.4.4","0.9.0","0.9.1","0.9.2","0.9.4","0.9.5","0.9.6","0.9.7","1.0.0","1.0.0rc11","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.0.6"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/djust/PYSEC-2026-4039.yaml"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
