Technical details
The GoCardless integration in Actual's sync-server uses console.log and console.debug to output API responses and error stack traces without filtering. The vulnerability stems from two code paths: (1) debug logging of complete GoCardless API account and transaction responses via console.debug in integration-bank.js, and (2) unhandled exception logging that dumps full error stack traces including HTTP headers containing Authorization bearer tokens in app-gocardless.js. Both vectors are reachable during normal operation (e.g., when calling GoCardless APIs or when upstream services return HTTP errors). The logged data flows to Docker logs and application log files, accessible to infrastructure operators and potentially exposed in centralized logging systems. Versions 25.10.0 and earlier are affected; patches available in 25.11.0 and later remove or redact sensitive data from logs.
