Summary

CVE-2026-4822 is a high-severity Insecure Temporary File (CWE-377) vulnerability in Iperiusbackup (inferred from references). Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 6th 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-6 (Least Privilege) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

is only possible with local access. A high degree of complexity is needed for the attack. The exploitability is told to be difficult. The exploit is now public and may be used. Upgrading to version 8.7.4 is able to address this issue. It is recommended to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-6 Least Privilege good match

AC-6 limits privileges granted to processes creating or accessing temporary files, reducing blast radius of insecure permissions.

SC-4 Information in Shared System Resources good match

SC-4 directly stops unauthorized information transfer through shared resources such as temporary files created with weak permissions.

AC-3 Access Enforcement partial match

AC-3 enforces file-system access authorizations so that temporary files cannot be read or modified by unauthorized processes.

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.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require avoiding insecure temp-file creation patterns.

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.8.28 Secure coding mostly match
prevents

Secure coding standards directly prohibit insecure temporary file creation and permissions.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect insecure temporary files but does not prevent their creation.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates secure handling of temporary files during design and coding.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify secure temporary-file creation and access controls.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture principles discourage insecure temporary-file patterns but do not directly address them.

A.8.3 Information access restriction partial match
prevents

Information access restriction can limit exposure but does not address file creation itself.
