• CVE-2024-8038: 0.21% estimated exploitation activity in the next 30 days; percentile 11.51 (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 An abstract UNIX domain socket responsible for introspection is available without authentication locally to any user with access to the network namespace where the local juju agent is running. On a juju controller agent, denial of service can be performed by using the /leases/revoke endpoint. Revoking leases in juju can cause availability issues. On a juju machine agent that is hosting units, disabling the unit component can be performed using the /units endpoint with a "stop" action.

# Patch Next advisory brief: CVE-2024-8038

Advisory: Vulnerable juju introspection abstract UNIX domain socket
IDs: CVE-2024-8038, GHSA-xwgj-vpm9-q2rq
Record: https://patchnext.com/advisories/cve-2024-8038 (revision 1, source checked 26 Oct 2026, 15:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/juju/juju 0.0.0-20240829052008-43f0fc59790d. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/juju/juju: affected < 0.0.0-20240829052008-43f0fc59790d; fixed in 0.0.0-20240829052008-43f0fc59790d

## Suggested inspection (read-only)
- Go github.com/juju/juju: check the installed version with your package manager.

## 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 github.com/juju/juju.
- 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.

## Sources
- Verified: https://github.com/advisories/GHSA-xwgj-vpm9-q2rq (GitHub-reviewed advisory GHSA-xwgj-vpm9-q2rq lists affected ranges: Go github.com/juju/juju >=0 <0.0.0-20240829052008-43f0fc59790d)
