What is CVE-2026-24332?

CVE-2026-24332 is a medium-severity vulnerability in Discord WebSocket API service, published on 22 Jan 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

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." NOTE: a third-party report suggests that this was remediated later in 2026.

Weakness: CWE-204
