Skupper uses a static cookie secret for the openshift oauth-proxy

CVE-2024-6535GHSA-w799-v85j-88pg

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/skupperproject/skupper 0.0.0-20240703184342-c26bce4079ff), 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.

Source description

As published by the source; long descriptions are shortened.

A flaw was found in Skupper. When Skupper is initialized with the console-enabled and with console-auth set to Openshift, it configures the openshift oauth-proxy with a static cookie-secret. In certain circumstances, this may allow an attacker to bypass authentication to the Skupper console via a specially-crafted cookie.

# Patch Next advisory brief: CVE-2024-6535

Advisory: Skupper uses a static cookie secret for the openshift oauth-proxy
IDs: CVE-2024-6535, GHSA-w799-v85j-88pg
Record: https://patchnext.com/advisories/cve-2024-6535 (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: High (CVSS 8.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/skupperproject/skupper 0.0.0-20240703184342-c26bce4079ff. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/skupperproject/skupper: affected < 0.0.0-20240703184342-c26bce4079ff; fixed in 0.0.0-20240703184342-c26bce4079ff

## Suggested inspection (read-only)
- Go github.com/skupperproject/skupper: 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/skupperproject/skupper.
- 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-w799-v85j-88pg (GitHub-reviewed advisory GHSA-w799-v85j-88pg lists affected ranges: Go github.com/skupperproject/skupper >=0 <0.0.0-20240703184342-c26bce4079ff)
