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.
Remediation advice
We recommend updating to the current version 6.4.6.1. You can get the update to 6.4.6.1 regularly via the Auto-Updater or directly via the download overview.

Workarounds
For older versions of 6.1, 6.2, and 6.3, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

- What is GHSA-R64M-QCHJ-HRJP? GHSA-R64M-QCHJ-HRJP is a critical-severity security vulnerability in shopware/core (composer), affecting versions <= 6.4.6.0. It is fixed in 6.4.6.1.
- Which packages are affected by GHSA-R64M-QCHJ-HRJP?
shopware/core(composer) (versions <= 6.4.6.0)shopware/platform(composer) (versions <= 6.4.6.0)
- Is there a fix for GHSA-R64M-QCHJ-HRJP? Yes. GHSA-R64M-QCHJ-HRJP is fixed in 6.4.6.1. Upgrade to this version or later.
- Is GHSA-R64M-QCHJ-HRJP exploitable, and should I be worried? Whether GHSA-R64M-QCHJ-HRJP 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-R64M-QCHJ-HRJP 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.
