CVE-2025-48929Known exploitationPublic exploitNetwork attack vector

Account access via reusable long-lived credentials

Published May 28, 2025 · Updated Jul 1, 2025

Insufficient session expiration in the TeleMessage service through 2025-05-05 allows remote attackers to access accounts using stolen credentials. The authentication service continues accepting long-lived credentials instead of expiring them or replacing them with short-lived tokens. An attacker must first obtain a credential; replay grants the associated account's access, with demonstrated disclosure of account data.
