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.","publishedAt":"2026-09-16T13:50:18.892Z","updatedAt":"2026-09-16T15:49:45.947Z","severity":{"score":7.4,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["djust-org djust"],"affected":[{"vendor":"djust-org","product":"djust","versions":[{"version":"< 1.0.7","status":"affected"}]}],"references":["https://github.com/djust-org/djust/security/advisories/GHSA-8g2f-g3gq-5rjv","https://github.com/djust-org/djust/releases/tag/v1.0.7"],"weaknesses":["CWE-306","CWE-668"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61590.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61590","state":"PUBLISHED","datePublished":"2026-09-16T13:50:18.892Z","dateUpdated":"2026-09-16T15:49:45.947Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-10T17:12:17.237Z"},"containers":{"cna":{"title":"djust's observability endpoints are network-exposed: the localhost gate is an opt-in middleware the docs omit, and the views enforce only DEBUG","descriptions":[{"lang":"en","value":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance.
