CVE-2026-33266

Use of Hard-coded Cryptographic Key vulnerability in Apache OpenMeetings. The remember-me cookie encryption key is set to default value in openmeetings.properties and not being auto-rotated. In case OM admin hasn't changed the default encryption key, an attacker who has stolen a cookie from a logged-in user can get full user credentials. This issue affects Apache OpenMeetings: from 6.1.0 before 9.0.0. Users are recommended to upgrade to version 9.0.0, which fixes the issue.

Summary		(es) Uso de vulnerabilidad de clave criptográfica codificada de forma rígida en Apache OpenMeetings. La clave de cifrado de la cookie ’recordarme’ está configurada con el valor predeterminado en openmeetings.properties y no se rota automáticamente.
