• CVE-2026-62286: 0.43% estimated exploitation activity in the next 30 days; percentile 36.80 (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.

Summary Dozzle supports per-user label filters in users.yml that are documented as an access-control boundary: "Filters are used to restrict the containers that a user can see" and "the guest user can only see containers with the label com.example.app … useful for restricting access to specific containers" (docs/guide/authentication.md). This is the mechanism operators use to give different users/tenants visibility into disjoint subsets of containers on the same host. The events stream handler streamEvents (GET /api/events/stream) honors that filter for the initial container list and for the incremental containers-changed updates, but it forwards two other channels — container-stat (live per-container CPU, memory, network and disk telemetry) and container-event (container lifecycle events: start/die/destroy/rename/pause/unpause, with the container's full attribute/label set) — to every authenticated client unconditionally, with no comparison against the caller's label filter.

# Patch Next advisory brief: CVE-2026-62286

Advisory: Dozzle label filters do not restrict container event and statistics streams
IDs: CVE-2026-62286, GHSA-xcw9-qmmf-vqxj
Record: https://patchnext.com/advisories/cve-2026-62286 (revision 3, source checked 26 Oct 2026, 15:29 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/amir20/dozzle 1.29.1-0.20260622172006-19c01e0fb491. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/amir20/dozzle: affected < 1.29.1-0.20260622172006-19c01e0fb491; fixed in 1.29.1-0.20260622172006-19c01e0fb491

## Suggested inspection (read-only)
- Go github.com/amir20/dozzle: 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/amir20/dozzle.
- 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.
