What is CVE-2023-37473?

CVE-2023-37473 is a high-severity security vulnerability in zenstruck/collection (composer), affecting versions < 0.2.1. It is fixed in 0.2.1.

How severe is CVE-2023-37473?

CVE-2023-37473 has a CVSS score of 8.5 (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 versions of zenstruck/collection are affected by CVE-2023-37473?

zenstruck/collection (composer) versions < 0.2.1 is affected.

Is there a fix for CVE-2023-37473?

Yes. CVE-2023-37473 is fixed in 0.2.1. Upgrade to this version or later.

Is CVE-2023-37473 exploitable, and should I be worried?

Whether CVE-2023-37473 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-2023-37473 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.

How do I fix CVE-2023-37473?

Upgrade zenstruck/collection to 0.2.1 or later.

Summary

zenstruck/collection passing callable string to EntityRepository::find() and query()

Workarounds

Do not allow passing user strings to EntityRepository::find() or query().

References

Fix commit.

Impact

Passing callable strings (ie system) caused the function to be executed.

CVE-2023-37473 has a CVSS score of 8.5 (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 (0.2.1); upgrading removes the vulnerable code path.

Affected versions

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.
