Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Forces removal or modification of permissions no longer required after reassignment, preventing improper preservation of old access rights.
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.
Enforcing least-privilege permission policies and reviews directly prevents incorrect permission propagation on copy/restore/share operations.
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.
Access-control policy defines how permissions must be preserved when objects are copied or shared.
Access-rights provisioning and review processes directly address the risk of overly permissive copied objects.
Privileged-access management includes rules for maintaining correct permissions on copied or restored data.
Information-access-restriction controls enforce least-privilege permissions that must be preserved during copy/restore operations.
Change-management procedures can require verification that permissions remain intact after modifications or restores.
Configuration baselines can embed permission settings, indirectly reducing the chance of incorrect preservation.
