Publisheddjust 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.

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Risk history
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
When does an EPSS score appear as a change?
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
Advisory history
1 saved versionsSee how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
How advisory history works
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
