CVE-2026-61590— djust's observability endpoints are network-exposed: the localhost gate is an opt-in middleware the docs omit, and the views enforce only DEBUG

Quick assessment

Affected
djust-org djust
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Vulnerability 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
Source: CVE Program / CVE List V5
Vulnerability Description
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.
