Vulnerability from github – Published: 2026-09-16 13:49 – Updated: 2026-09-16 13:49

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

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.

Patches

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.

Workarounds

Ensure DEBUG=False in production, and do not expose the observability endpoints to untrusted networks.

Severity

7.4 (High)

CVE-2026-61590 (GCVE-0-2026-61590)

Vulnerability from cvelistv5 – Published: 2026-09-16 13:50 – Updated: 2026-09-16 15:49

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

Summary

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.
