Summary
Workarounds
For older versions of 6.2, 6.3, and 6.4, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.
Impact
Shopware has a new Twig Tag sw_silent_feature_call which silences deprecation messages while triggered in this tag.
It accepts as parameter a string the feature flag name to silence, but this parameter is not escaped properly and allows execution of code.
Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.
CVE-2024-42355 has a CVSS score of 8.3 (High). The vector is network-reachable, low privileges required, and no user interaction. 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. A fixed version is available (6.5.8.13, 6.6.5.1); upgrading removes the vulnerable code path.

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
Update to Shopware 6.6.5.1 or 6.5.8.13
Frequently Asked Questions
- What is CVE-2024-42355? CVE-2024-42355 is a high-severity code injection vulnerability in shopware/core (composer), affecting versions <= 6.5.8.12. It is fixed in 6.5.8.13, 6.6.5.1. Untrusted input is evaluated as executable code within the application's runtime environment.
- How severe is CVE-2024-42355? CVE-2024-42355 has a CVSS score of 8.3 (High). 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 packages are affected by CVE-2024-42355?
shopware/core(composer) (versions <= 6.5.8.12)shopware/platform(composer) (versions <= 6.5.8.12)
- Is there a fix for CVE-2024-42355? Yes. CVE-2024-42355 is fixed in 6.5.8.13, 6.6.5.1. Upgrade to this version or later.
- Is CVE-2024-42355 exploitable, and should I be worried? Whether CVE-2024-42355 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-2024-42355 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.
