Summary
Improper Authorization in @sap-cloud-sdk/core
Affected versions of @sap-cloud-sdk/core do not properly validate JWTs. The verifyJwt() function does not properly validate the URL from where the public verification key for the JWT can be downloaded. Any URL was trusted which makes it possible to provide a URL belonging to a manipulated JWT.

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.

Frequently Asked Questions
- What is GHSA-R2VW-JGQ9-JQX2? GHSA-R2VW-JGQ9-JQX2 is a high-severity security vulnerability in @sap-cloud-sdk/core (npm), affecting versions >= 1.19.0, < 1.21.2. It is fixed in 1.21.2.
- Which versions of @sap-cloud-sdk/core are affected by GHSA-R2VW-JGQ9-JQX2? @sap-cloud-sdk/core (npm) versions >= 1.19.0, < 1.21.2 is affected.
- Is there a fix for GHSA-R2VW-JGQ9-JQX2? Yes. GHSA-R2VW-JGQ9-JQX2 is fixed in 1.21.2. Upgrade to this version or later.
- Is GHSA-R2VW-JGQ9-JQX2 exploitable, and should I be worried? Whether GHSA-R2VW-JGQ9-JQX2 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 GHSA-R2VW-JGQ9-JQX2 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.
