cwe-601-open-redirect

To fix a CWE-601 open redirect vulnerability in Java, validate redirect URLs against an allowlist and reject external host or protocol mismatches. This Skill automatically remediates insecure redirection patterns to prevent unauthorized user redirection.

An open redirect vulnerability occurs when an application redirects users to untrusted sites via manipulated URLs. URL validation prevents this by enforcing an allowlist of permitted destinations and rejecting external host or protocol mismatches in Java redirect logic.

Validate redirect URLs against an allowlist in Java by checking requested destinations against approved hosts and rejecting external protocol mismatches. This remediates CWE-601 findings by ensuring redirect logic only permits authorized internal routing.

Yes, you can use this to remediate SAST findings for insecure URL redirection. It applies deterministic fixes to flagged Java code by implementing URL validation and allowlisting to secure login or callback handlers against CWE-601 vulnerabilities.

Yes, this URL redirect remediation works with Java login and callback handlers. It targets insecure redirect logic within these specific workflows, applying URL validation and allowlist enforcement to prevent unauthorized external redirection.

The limitation of using an allowlist for open redirect remediation is that it requires strict maintenance of permitted hosts and protocols. Any external host or protocol mismatch not explicitly defined in the allowlist will be rejected, potentially blocking legitimate redirects.
