JWT Monitor
Summary: PortSwigger's BApp Store lists a Burp Suite extension called JWT Monitor, built by Patrick Schmid of Redguard AG, that watches a supplied JWT token for expiration and swaps any existing JWT tokens in outgoing requests with the monitored one. Version 1.1.1, last updated 18 September 2025, also offers an autopilot mode that pauses task execution as the token nears expiry and resumes when a new token with sufficient validity is supplied, handling Bearer tokens in Authorization headers and cookies that begin with eyJ.
Key Takeaway: The extension exists because testers lose work when a token expires mid-run, and it works by automatically replacing tokens in outgoing traffic - a reminder that whoever holds a valid JWT is treated as the user until it lapses.
