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

Noroxi assessment

Priority: Monitor (action score 29/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.35% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
Fixed version: djust (PyPI) 1.0.7.

Low priority for now. Upgrade to djust (PyPI) 1.0.7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
