Accguard – authorization regression testing for APIs
Accguard is a tool designed for authorization regression testing of APIs using real authenticated traffic. It identifies when an authenticated user can access resources that they should not, addressing a common vulnerability in APIs. By leveraging existing test suites, Accguard provides precise detection of unauthorized data exposure without requiring changes to the test code.
- ▪Accguard detects broken access control by confirming unauthorized data replay between users.
- ▪The tool operates as a local HTTP proxy, silently recording authenticated requests during tests.
- ▪Accguard uses hash comparisons to determine if different users receive identical responses, flagging potential security issues.

accguard Authorization regression testing from real authenticated traffic. Authentication proves who you are. Authorization proves what you can access. accguard detects when those boundaries fail: authenticated user ≠ authorized user Broken access control remains the most common high-impact API vulnerability. Existing scanners can't reliably catch it — they don't have authenticated context. They've never logged into your app. Your test suite has that context. accguard uses it. Try the BOLA demo git clone https://github.com/rodrigo-areyzaga/accguard-bola-demo cd accguard-bola-demo npm install npm run demo Under 90 seconds from clone to confirmed authorization regression.
