CVE-2025-69233: Apache CloudStack: Domain/account resources limits not honored

["Piotr P. Karwasz" <pkarwasz () apache org>]

Severity: moderate

Affected versions:

- Apache CloudStack 4.0.0 through 4.20.2.0
- Apache CloudStack 4.21.0.0 through 4.22.0.0

Description:

Due to multiple time-of-check time-of-use race conditions in the
resource count check and increment logic, as well as missing
validations, users of the platform are able to exceed the allocation
limits configured for their accounts/domains. This can be used by an
attacker to degrade the infrastructure's resources and lead to denial of
service conditions.

Users are recommended to upgrade to Apache CloudStack versions 4.20.3.0
or 4.22.0.1, or later, which fixes this issue.
