Imagine being a subscriber to Anthropic’s Claude Max and suddenly realising that despite not even wandering around your laptop and opening the app, token usage keeps mounting.

KazaSec's take
Token and session-handling flaws like this are common precisely because they're easy to get subtly wrong, a token that never expires, a signature that isn't actually verified, a session that survives a password reset. They're also exactly the kind of issue a manual security review is built to catch.
