EPSS

• CVE-2026-61590: 0.36% estimated exploitation activity in the next 30 days; percentile 29.41 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact djust's observability endpoints expose live view/session state and a remote method-invocation surface (evalhandler). 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 evalhandler 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.

# Patch Next advisory brief: CVE-2026-61590

Advisory: djust's observability endpoints are network-exposed: the localhost gate is an opt-in middleware the docs omit, and the views enforce only DEBUG
IDs: CVE-2026-61590, GHSA-8g2f-g3gq-5rjv
Record: https://patchnext.com/advisories/cve-2026-61590 (revision 3, source checked 26 Oct 2026, 13:51 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: djust 1.0.7. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI djust: affected < 1.0.7; fixed in 1.0.7

## Suggested inspection (read-only)
- `python -m pip show djust`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on djust.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
