GHSA-984H-8PHV-MF43

Vulnerability from github – Published: 2026-01-22 09:31 – Updated: 2026-01-22 09:31

Details

Discord through 2026-01-16 allows gathering information about whether a user's client state is Invisible (and not actually offline) because the response to a WebSocket API request includes the user in the presences array (with "status": "offline"), whereas offline users are omitted from the presences array. This is arguably inconsistent with the UI description of Invisible as "You will appear offline."

Severity ?

4.3 (Medium)
