Summary
CVE-2026-110237 is a high-severity Unverified Ownership (CWE-283) vulnerability in Hackmd (inferred from references). Its CVSS base score is 7.0 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-16 (Security and Privacy Attributes) and AC-24 (Access Control Decisions) — see the control section below for these in your framework.

Vulnerability Data
Vifm 0.8.1-beta through 0.14.4 reuses a pre-existing IPC FIFO in the shared temporary directory without checking ownership, allowing local users to execute commands as another user. Attackers can pre-create a world-writable vifm-ipc-vifm FIFO and write IPC packets with -c and…

Mitigating Controls (NIST 800-53 r5) AI
Associating ownership as a security attribute enables subsequent verification of resource ownership.
Requiring access decisions to consider all relevant attributes includes ownership verification.
A reference monitor provides the tamperproof mechanism that can enforce ownership checks.
Access enforcement directly requires verifying ownership before granting access to resources.

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 defined access permissions and authorizations directly prevents missing ownership verification for resources.
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 policies can require ownership verification before granting access to critical resources.
Identity management processes can include verification of resource ownership during provisioning and access decisions.
A.5.18 governs the provisioning, review, and revocation of access rights based on authorization and policy; it does not verify resource ownership and cannot stop exploitation of unverified ownership.
A.8.2 controls the allocation, review, expiry and use of privileged rights via authorization and least-privilege rules; it has no bearing on whether a resource's ownership is verified before use, so the CWE-283 weakness can still be present and exploited.
