Description

A resource release flaw in Apache CloudStack's scoped global configuration can cause resource exhaustion, potentially leading to denial of service (DoS) on the management server. This affects multiple modules including Quota and Host-HA. Versions from 4.7.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0 are vulnerable. Upgrading to 4.20.3.1 or 4.22.1.1 or later resolves the issue.

Technical Analysis

CVE-2026-59654 describes a Missing Release of Resource after Effective Lifetime vulnerability in Apache CloudStack's scoped global configuration functionality. This defect impacts various modules and plugins of the CloudStack management server, such as Quota and Host-HA, by failing to release resources after their effective lifetime ends. This can lead to resource exhaustion and an eventual denial of service condition on the management server. The vulnerability affects Apache CloudStack versions from 4.7.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. The issue is fixed in versions 4.20.3.1 and 4.22.1.1 or later.

Potential Impact

The vulnerability can cause a denial of service (DoS) on the Apache CloudStack management server by exhausting resources due to failure to release them after their effective lifetime. This impacts availability but does not affect confidentiality or integrity.

Mitigation Recommendations

Users should upgrade Apache CloudStack to version 4.20.3.1, 4.22.1.1, or later to remediate this vulnerability. These versions include the official fix for the resource release issue. No other mitigation is indicated.
