CORS
Definition: CORS (Cross-Origin Resource Sharing) is a browser mechanism that allows controlled access to resources from different domains.
Purpose: It extends the same-origin policy (SOP) to enable more flexible interactions between websites.
Vulnerabilities: Poorly configured CORS policies can lead to cross-domain attacks, such as data theft or unauthorized access.
Limitations: CORS does not protect against all types of cross-origin attacks, including CSRF (Cross-Site Request Forgery).
Same-Origin Policy: SOP restricts how a document or script can interact with resources from different origins to prevent malicious activities.
Relaxation Mechanism: CORS allows a controlled relaxation of SOP using HTTP headers that specify trusted origins and access permissions.
