{"id":"CVE-2026-61590","aliases":["GHSA-8g2f-g3gq-5rjv","PYSEC-2026-4039"],"url":"https://o3.security/vulnerability/CVE-2026-61590","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":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, djust'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. This issue is fixed 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. As a workaround, ensure `DEBUG=False` in production, and do not expose the observability endpoints to untrusted networks.","published":"2026-09-16T13:50:18.892Z","modified":"2026-10-28T02:30:22.469971935Z","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"djust","fixedVersion":"1.0.7"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/djust-org/djust/releases/tag/v1.0.7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61590.json"},{"type":"ADVISORY","url":"https://github.com/djust-org/djust/security/advisories/GHSA-8g2f-g3gq-5rjv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61590"},{"type":"PACKAGE","url":"https://github.com/djust-org/djust"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:22.469971935Z"}}
