CVE-2026-54367 is an authentication bypass vulnerability affecting Gladinet CentreStack versions prior to 17.2. Exposed API endpoints fail to enforce proper authorization checks on account settings operations, allowing unauthenticated attackers to read, modify, or delete arbitrary account settings. The flaw is compounded by the use of a static shared encryption key that allows attackers to generate valid encrypted EntAcctId values and forge identifiers corresponding to arbitrary user GUIDs, including the system-wide cluster settings account. Successful exploitation enables unauthorized access to sensitive configuration data and administrative metadata, including hosted tenant domain and administrator identity enumeration.
