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
- Explicitly whitelist trusted origins
- Avoid reflecting dynamic origins
