HIGHCVSS 7.4/10

Last modified

CVE-2026-61590 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. 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`).

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.
