What is CVE-2020-24402?

CVE-2020-24402 is a medium-severity security vulnerability in magento/community-edition (composer), affecting versions < 2.3.6. It is fixed in 2.3.6, 2.4.1.

How severe is CVE-2020-24402?

CVE-2020-24402 has a CVSS score of 4.9 (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.

Which packages are affected by CVE-2020-24402?

magento/community-edition (composer) versions < 2.3.6; magento/project-community-edition (composer) versions <= 2.0.2.

Is there a fix for CVE-2020-24402?

Yes. CVE-2020-24402 is fixed in 2.3.6, 2.4.1. Upgrade to this version or later.

Is CVE-2020-24402 exploitable, and should I be worried?

Whether CVE-2020-24402 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-2020-24402 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.

Summary

Magento version 2.4.0 and 2.3.5p1 (and earlier) are affected by an incorrect permissions vulnerability in the Integrations component. This vulnerability could be abused by authenticated users with permissions to the Resource Access API to delete customer details via the REST API without authorization.

Impact

CVE-2020-24402 has a CVSS score of 4.9 (Medium). The vector is network-reachable, high 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 (2.3.6, 2.4.1); upgrading removes the vulnerable code path.

Affected versions

magento/community-edition (< 2.3.6) magento/community-edition (= 2.4.0) magento/project-community-edition (<= 2.0.2)

Security releases

magento/community-edition → 2.3.6 (composer) magento/community-edition → 2.4.1 (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.
