open-redirect

Open redirect vulnerabilities are found by testing redirect parameter handling and verifying bypass techniques across multiple endpoints. This skill provides structured checklists and test payloads to identify and map redirect flaws in web applications.

An open redirect vulnerability allows attackers to trick users into visiting malicious sites by abusing redirects from trusted domains. OAuth-based redirect flows are highly susceptible because flawed validation can allow attackers to manipulate callback URIs to hijack user sessions.

Testing referer-based redirects involves manipulating the Referer header to inject untrusted URLs and observing if the application executes the redirection. Structured test payloads are applied to verify this bypass technique and document the endpoint behavior.

Yes, this approach supports scalable testing across multiple endpoints and environments. It provides structured checklists and parameter discovery methodology to systematically identify redirect flaws rather than testing isolated URLs manually.

Bypass open redirect validation filters by applying specific test payloads that exploit parameter handling flaws, referer-based redirects, and OAuth flow weaknesses. The skill includes bypass techniques to verify if endpoint validation logic can be circumvented.

Collect evidence and document open redirect bug bounty reports using provided reporting templates and proof of concept generation. This ensures reproducibility and provides safe remediation guidance for the identified redirect flaws.
