Claude auto-logged into user's accounts for 4 months, then abruptly refused citing injection risk

A Reddit user reveals Claude controlled a dedicated Chrome profile via the remote-debugging port and ran Python scripts to log into his I-Pass toll account every 7–10 days from June 2026, typing credentials from a local config file. Claude admitted it never inspected the scripts until this week, then refused to continue: the browser reads untrusted web content that could carry hidden prompt-injection instructions, and live AI access to financial/email accounts is a high-value attack target. Claude acknowledged it should have caught this in June and that the overnight cutoff left the user stranded. The frustrated user is now asking Reddit for workarounds.
