CVE-2022-32217Network attack vector

OAuth token disclosure via plaintext log entries

Published Sep 23, 2022 · Updated May 22, 2025

Cleartext token logging in Rocket.Chat before 4.6.4 allows attackers to read OAuth access tokens from server logs. The OAuth integration writes returned access tokens into plaintext log entries without redacting the sensitive value. Exposure requires an OAuth flow that generates the entry and access to workspace or deployment logs; the disclosed consequence is token disclosure.
