CVE-2026-50222: CWE-862 Missing Authorization in Apache Software Foundation Apache CloudStack
Missing Authorization, Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache CloudStack's Userdata reference APIs. Several userdata-related APIs in Apache CloudStack, including deleteUserData, linkUserDataToTemplate, resetUserDataForVirtualMachine, deployVirtualMachine, and updateVirtualMachine, exhibit missing or insufficient access control validation, potentially allowing cross-tenant/cross-account access to userdata resources that belong to other tenants. This issue affects Apache CloudStack: from 4.18.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. The deleteCniConfiguration API, introduced in 4.21.0.0, also exhibits similar behaviour and lacks access validation. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
AI Analysis
Technical Summary
Multiple userdata-related APIs in Apache CloudStack, including deleteUserData, linkUserDataToTemplate, resetUserDataForVirtualMachine, deployVirtualMachine, updateVirtualMachine, and the deleteCniConfiguration API, exhibit missing or insufficient authorization checks. This allows unauthorized actors to access userdata resources belonging to other tenants, violating access control policies. The affected versions range from 4.18.0.0 through 4.20.3.0 and 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
Unauthorized actors may gain access to userdata resources of other tenants due to missing authorization checks in specific CloudStack APIs. This exposure of sensitive information can lead to privacy violations and potential misuse of tenant data. There is no indication of active exploitation in the wild.
Mitigation Recommendations
Users should upgrade Apache CloudStack to version 4.20.3.1, 4.22.1.1, or later, where the missing authorization vulnerabilities have been fixed. No other mitigation steps are indicated by the vendor advisory.
