CVE-2025-66172
Apache Cloudstack 4.21.0.0 – 4.22.0.1
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-66172 is a high-severity Exposure of Private Personal Information to an Unauthorized Actor (CWE-359) vulnerability in Apache Cloudstack. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 42th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-21 (Information Sharing) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data
The CloudStack Backup plugin has an improper access logic in versions 4.21.0.0 and 4.22.0.0. Anyone with authenticated user-account access in CloudStack 4.21.0.0+ environments, where this plugin is enabled and have access to specific APIs can restore a volume from any…

Mitigating Controls (NIST 800-53 r5) AI
Enforces authorizations so that PII is not reachable by unauthorized actors.
Requires explicit verification that a recipient's authorizations match the sensitivity of shared PII.
Limits granted rights to the minimum needed, reducing the set of actors who can reach private data.
Documents the legal or consent basis required before any processing of PII occurs.
Implements consent mechanisms that directly block access absent the individual's permission.
Encrypts or otherwise protects stored PII against unauthorized retrieval.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
CWE-359 does not impair RC.CO-04's ability to issue approved public recovery updates, yet any resulting PII exposure can partially undermine the outcome's overall efficacy and trust.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.34 only requires a policy, procedures, roles (e.g. privacy officer) and unspecified 'appropriate' measures; it does not itself stop unauthorized access to PII and depends on other controls (e.g. access enforcement) to do so, per the owner's explicit rule on dependency vs. effect.
Hardening callouts derived
Configuration rules from DISA STIG baselines that bear on weaknesses of the type cited by this CVE. Each rule is shown with the relationship its mapping actually records, against the CWE it was authored against.
