Summary
github.com/gitpod-io/gitpod vulnerable to Cookie Tossing
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.
Impact
CVE-2024-21583 has a CVSS score of 4.1 (Medium). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- How severe is CVE-2024-21583? CVE-2024-21583 has a CVSS score of 4.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of github.com/gitpod-io/gitpod are affected by CVE-2024-21583? github.com/gitpod-io/gitpod (go) versions <= 0.8.0 is affected.
- Is there a fix for CVE-2024-21583? No fixed version is listed for CVE-2024-21583 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2024-21583 exploitable, and should I be worried? Whether CVE-2024-21583 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2024-21583 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
