Goploy: Arbitrary File Read via Path Traversal in /deploy/fileDiff allows Remote Server Compromise

CVE-2026-53553GHSA-4g5x-hcwm-82jw

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/zhenorzz/goploy 1.18.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2026-53553

Advisory: Goploy: Arbitrary File Read via Path Traversal in /deploy/fileDiff allows Remote Server Compromise
IDs: CVE-2026-53553, GHSA-4g5x-hcwm-82jw
Record: https://patchnext.com/advisories/cve-2026-53553 (revision 3, source checked 28 Oct 2026, 06:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/zhenorzz/goploy 1.18.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/zhenorzz/goploy: affected < 1.18.0; fixed in 1.18.0

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