• CVE-2024-21583: 0.60% estimated exploitation activity in the next 30 days; percentile 48.63 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

This allows an adversary who controls a subdomain to set the value of the cookie on the Gitpod control plane, which can be assigned to an attacker’s own JWT so that specific actions taken by the victim (such as connecting a new Github organization) are…

# Patch Next advisory brief: CVE-2024-21583

Advisory: github.com/gitpod-io/gitpod vulnerable to Cookie Tossing
IDs: CVE-2024-21583, GHSA-8pgc-65mj-53h5
Record: https://patchnext.com/advisories/cve-2024-21583 (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 5.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/gitpod-io/gitpod: affected <= 0.8.0

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/gitpod-io/gitpod.
- 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-8pgc-65mj-53h5 (GitHub-reviewed advisory GHSA-8pgc-65mj-53h5 lists affected ranges: Go github.com/gitpod-io/gitpod >=0 <=0.8.0)

Commands are suggestions: review each one before running it.
