## Summary

OpenPanel, an open-source web analytics platform, is affected in versions before 3.0.0. An unauthenticated attacker can exploit a missing authorization check in its event.bots API to view bot event names, types, and page paths for private or password-protected projects, which exposes internal routes.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Openpanel-dev openpanel: fixed in 3.0.0

## Description

OpenPanel before 3.0.0 contains a missing authorization vulnerability in the event.bots tRPC procedure that allows unauthenticated attackers to read bot events by only checking shareOverview row existence. Attackers can send anonymous requests with a projectId to retrieve bot-event names, types, and paths for private or password-protected projects, revealing internal routes.
