• CVE-2026-30225: 0.46% estimated exploitation activity in the next 30 days; percentile 39.96 (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 An authentication context confusion vulnerability in RestartAction allows a low‑privileged authenticated user to execute actions they are not permitted to run. RestartAction constructs a new internal connect.Request without preserving the original caller’s authentication headers or cookies. When this synthetic request is passed to StartAction, the authentication resolver falls back to the guest user. If the guest account has broader permissions than the authenticated caller, this results in privilege escalation and unauthorized command execution. This vulnerability allows a low‑privileged authenticated user to bypass ACL restrictions and execute arbitrary configured shell actions. Details Affected files: service/internal/api/api.go service/internal/auth/authcheck.go Relevant code in RestartAction: Authentication in StartAction: Issue: 1. RestartAction creates a new connect.Request object. 2. The new request does not preserve caller headers or cookies. 3. UserFromApiCall()…

# Patch Next advisory brief: CVE-2026-30225

Advisory: OliveTin's RestartAction always runs actions as guest
IDs: CVE-2026-30225, GHSA-p443-p7w5-2f7f
Record: https://patchnext.com/advisories/cve-2026-30225 (revision 1, source checked 26 Oct 2026, 15:15 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/OliveTin/OliveTin 0.0.0-20260305000458-cb46a597b246. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/OliveTin/OliveTin: affected < 0.0.0-20260305000458-cb46a597b246; fixed in 0.0.0-20260305000458-cb46a597b246

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