CVE-2025-69233 Apache CVE debrief

CVE-2025-69233 affects Apache CloudStack and was published on 2026-05-08, with a modification on 2026-05-09. The issue is a set of time-of-check time-of-use race conditions plus missing validations in resource count check and increment logic. In practice, that can let users exceed account or domain allocation limits, which may degrade infrastructure resources and create denial-of-service conditions. Apache’s advisory says the issue is fixed in CloudStack 4.20.3.0 and 4.22.0.1, or later.

Who should care

Apache CloudStack operators, cloud platform administrators, and tenants or service teams that rely on CloudStack-enforced account or domain allocation limits. Environments running affected versions are the primary concern, especially where resource quotas are used to control compute, storage, or similar consumable capacity.

Technical summary

NVD lists affected Apache CloudStack versions from 4.0.0 up to, but not including, 4.20.3.0, and from 4.21.0.0 up to, but not including, 4.22.0.1. The weakness is described as race conditions in resource count checking and incrementing, combined with missing validations. NVD maps the issue to CVSS v3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H and weaknesses CWE-367 and CWE-770. The practical impact is quota bypass leading to resource exhaustion and service degradation.

Defensive priority

Medium priority, with prompt patching recommended because the impact is availability loss in an infrastructure control plane.

Recommended defensive actions

  • Upgrade Apache CloudStack to 4.20.3.0, 4.22.0.1, or a later fixed release.
  • Review account and domain allocation controls for abnormal consumption patterns while patching is planned.
  • Check vendor advisory and release notes for any additional operational guidance tied to the fixed versions.
  • Prioritize remediation in environments where allocation limits are relied on to protect shared infrastructure capacity.
