CVE-2026-75932Network attack vector

OAuth secret theft via cross-tenant domain reassignment

Published Aug 21, 2026 · Updated Aug 21, 2026

Missing authorization in Jet Admin allows remote attackers to reroute custom-domain traffic and disclose OAuth client credentials. The custom-domain binding workflow accepts a domain assigned to another tenant, permits the new workspace to edit its authentication configuration, and copies the victim tenant's OAuth Client ID and Client Secret into the attacker's workspace. A target must use a custom domain; OAuth credential disclosure additionally requires an OAuth authentication provider, while domain traffic can be redirected to the malicious app.
