CVE-2026-33388 PUBLISHED

Incorrect authorization in Credentials Manager in Guardian/CMC before 26.3.0

Assigner: Nozomi
Reserved: 19.03.2026 Published: 08.09.2026 Updated: 08.09.2026

An access control vulnerability was discovered in the Credentials Manager functionality due to insufficient validation of user privileges. A remote authenticated user with limited privileges can view a limited subset of the available entries in the Credentials Manager. The actual credential values are not directly visible, but the user can delete entries or edit their properties. An attacker who deletes or edits an entry can disrupt authentication for dependent devices, and one who manipulates an entry's configuration may be able to indirectly obtain the credentials.
