Cross-Origin-Opener-Policy Misconfiguration

Description

Inadequate protection of browsing context can compromise sensitive data by allowing untrusted documents to share the same context, leading to potential data leaks.

Recommendation

To prevent unauthorized access, configure your web server/application to set the Cross-Origin-Opener-Policy header with a value of ‘same-origin’. Consider using modern browsers that support this feature for enhanced security.
