CVE-2026-61422: CWE-918 Server-Side Request Forgery (SSRF) in Apache Software Foundation Apache CloudStack
Authenticated pre-validation SSRF vulnerability in Apache CloudStack's template and ISO registration functionality. When registering a template or ISO, CloudStack makes a live HTTP HEAD/GET call to determine file size for secondary storage usage-limit checks, and this happens before URL validation is performed. However, this does not pose a malicious template or ISO registration risk, as URL validation still occurs prior to the actual download by the Secondary Storage VM.This issue affects Apache CloudStack: in 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. 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
This vulnerability in Apache CloudStack allows an authenticated user to trigger SSRF during the template or ISO registration process. Specifically, CloudStack makes live HTTP HEAD/GET calls to the provided URL before validating it, potentially allowing SSRF attacks. However, the risk of malicious template or ISO registration is mitigated by subsequent URL validation before download by the Secondary Storage VM. The affected versions are 4.20.3.0 and 4.21.0.0 through 4.22.1.0. The vendor recommends upgrading to 4.20.3.1 or 4.22.1.1 or later to remediate the issue.
Potential Impact
An authenticated attacker could exploit this SSRF vulnerability to make unintended HTTP requests from the server during template or ISO registration. This could potentially be used to access internal resources or services not otherwise accessible. However, the vulnerability does not allow malicious template or ISO registration due to later URL validation steps.
Mitigation Recommendations
Users should upgrade Apache CloudStack to version 4.20.3.1, 4.22.1.1, or later, where this SSRF vulnerability is fixed. No other mitigations are specified. Patch status is confirmed by vendor recommendation.
