Impact

It is possible to put the same line item multiple one in the cart using API, the Cart Validators checked the line item's individuality and the user was able to skip the clearance sale in cart

The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.

CVE-2023-22730 has a CVSS score of 6.3 (Medium). 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 (6.4.18.1); upgrading removes the vulnerable code path.

Affected versions

shopware/platform (<= 6.4.18.0) shopware/core (<= 6.4.18.0)

Security releases

shopware/platform → 6.4.18.1 (composer) shopware/core → 6.4.18.1 (composer)

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

  1. What is CVE-2023-22730? CVE-2023-22730 is a medium-severity improper input validation vulnerability in shopware/platform (composer), affecting versions <= 6.4.18.0. It is fixed in 6.4.18.1. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
  2. How severe is CVE-2023-22730? CVE-2023-22730 has a CVSS score of 6.3 (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.
  3. Which packages are affected by CVE-2023-22730?
    • shopware/platform (composer) (versions <= 6.4.18.0)
    • shopware/core (composer) (versions <= 6.4.18.0)
  4. Is there a fix for CVE-2023-22730? Yes. CVE-2023-22730 is fixed in 6.4.18.1. Upgrade to this version or later.
  5. Is CVE-2023-22730 exploitable, and should I be worried? Whether CVE-2023-22730 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.

  6. What actually determines whether CVE-2023-22730 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.
  7. How do I fix CVE-2023-22730?
    • Upgrade shopware/platform to 6.4.18.1 or later
    • Upgrade shopware/core to 6.4.18.1 or later
