## Overview

ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0 of ApostropheCMS and 1.6.1 of passport-bridge, cross-host or cross-locale session migration places a single-use bearer session token in a redirect URL. A client that obtains and redeems a still-valid, unconsumed token before its first use can adopt the associated session, including through the passport-bridge cross-locale flow. This issue is fixed in ApostropheCMS 4.33.0 and passport-bridge 1.6.1.

## Affected

- `apostrophe < 4.33.0`
