OAUTH Scan

Summary: PortSwigger's BApp Store lists OAUTH Scan, a Burp Suite extension by Maurizio Siddu, version 1.2, that provides a way to discover OAuth v2 and OpenID vulnerabilities. The listing was last updated on 03 December 2024, carries an overall system impact rating of Low, and notes that extensions are written by third-party users of Burp and come with no warranty from PortSwigger.

Key Takeaway: OAuth and OpenID are the authentication paths behind much of your single sign-on, and this is a third-party extension PortSwigger explicitly does not vouch for - so any team running it against production identity flows is trusting code the vendor disclaims.
