Work Description: salcho opened a new pull request #426:
URL: https://github.com/apache/struts/pull/426
Hello Struts devs,
This PR builds Fetch Metadata support on for Struts2, namely:
- If a request has `Sec-Fetch-*` headers (i.e. comes from a modern browser),
the Fetch Metadata Interceptor will reject the request if it is requested
cross-site (a potential CSRF attack).
- One default Resource Isolation Policy is provided based on
https://web.dev/fetch-metadata/, which prevents all major cross-site request
forgery attacks.
- This Interceptor gives the ability to add exemptions to this security
mitigation, that is: URLs that are meant to be accessed cross-site.
- The Fetch Metadata Interceptor has been added to the default interceptor
stack.
- The `Vary` header has been added to responses to ensure that any cached
responses include Fetch Metadata headers in their key. This is an added layer
of security against cache poisoning.
