Real-World Exposure
github.com/gitpod-io/gitpodReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Versions of the package github.com/gitpod-io/gitpod/components/server/go/pkg/lib before main-gha.27122; versions of the package github.com/gitpod-io/gitpod/components/ws-proxy/pkg/proxy before main-gha.27122; versions of the package github.com/gitpod-io/gitpod/install/installer/pkg/components/auth before main-gha.27122; versions of the package github.com/gitpod-io/gitpod/install/installer/pkg/components/public-api-server before main-gha.27122; versions of the package github.com/gitpod-io/gitpod/install/installer/pkg/components/server before main-gha.27122; versions of the package @gitpod/gitpod-protocol before 0.1.5-main-gha.27122 are vulnerable to Cookie Tossing due to a missing __Host- prefix on the gitpod_io_jwt2 session cookie. 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 actioned by the attackers session.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/gitpod-io/gitpod, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of github.com/gitpod-io/gitpod for CVE-2024-21583. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
