How to Fix CVE-2025-53092

To remediate this vulnerability, upgrade all affected @strapi/core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@strapi/core fixed: 5.20.0 
npm install @strapi/core@5.20.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @strapi/core

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-53092, inspect your project dependencies using npm:

npm ls @strapi/core

Analyze the terminal output to locate any version of @strapi/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.20.0), your application is affected.

Note: The npm ls @strapi/core command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-364: Signal Handler Race Condition, where the product uses a signal handler that introduces a race condition. In @strapi/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary A CORS misconfiguration vulnerability exists in default installations of Strapi where attacker-controlled origins are improperly reflected in API responses. ### Technical Details By default, Strapi reflects the value of the Origin header back in the Access-Control-Allow-Origin response header without proper validation or whitelisting. Example: `Origin: http://localhost:8888` `Access-Control-Allow-Origin: http://localhost:8888` `Access-Control-Allow-Credentials: true` This allows an attacker-controlled site (on a different port, like 8888) to send credentialed requests to the Strapi backend on 1337. ### Suggested Fix 1. Explicitly whitelist trusted origins 2. Avoid reflecting dynamic origins
