CVE-2025-53092 (GCVE-0-2025-53092)

Vulnerability from cvelistv5 – Published: 2025-10-16 16:29 – Updated: 2025-10-16 18:13

Title

Strapi core vulnerable to sensitive data exposure via CORS misconfiguration

Summary

Strapi is an open source headless content management system. Strapi versions prior to 5.20.0 contain a CORS misconfiguration vulnerability in default installations. By default, Strapi reflects the value of the Origin header back in the Access-Control-Allow-Origin response header without proper validation or whitelisting. This allows an attacker-controlled site to send credentialed requests to the Strapi backend. An attacker can exploit this by hosting a malicious site on a different origin (e.g., different port) and sending requests with credentials to the Strapi API. The vulnerability is fixed in version 5.20.0. No known workarounds exist.

Severity

6.5 (Medium)

GHSA-9329-MXXW-QWF8

Vulnerability from github – Published: 2025-10-16 19:49 – Updated: 2026-01-29 03:59

Summary

Strapi core vulnerable to sensitive data exposure via CORS misconfiguration

Details

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

Severity

7.5 (High)
