## Technical details

The vulnerability is an information disclosure flaw in Apache CloudStack's LDAP authentication plugin. The listLdapConfigurations API fails to enforce proper access controls, allowing any authenticated user with default roles to retrieve LDAP provider configurations including sensitive settings. No special privileges or additional preconditions are required beyond having a valid user account. An attacker can invoke this API to enumerate and extract LDAP configuration details that should be restricted to administrators, potentially compromising the underlying directory service.

## Affected products

- Apache CloudStack 4.2.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0

## Timeline

- 2026-08-21: disclosed
- 2026-08-21: patched: Fixed in versions 4.20.3.1, 4.22.1.1 and later
