CVE-2025-53092
Strapi core vulnerable to sensitive data exposure via CORS misconfiguration
Description
### 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
