Summary

CVE-2026-29064 is a high-severity Path Traversal (CWE-22) vulnerability in Lfprojects Zarf. Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Malicious File (T1204.002); ranked at the 12.4th 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-29064 is a path traversal vulnerability (CWE-22) in Zarf, an air-gapped native package manager for Kubernetes. The issue affects versions from 0.54.0 up to but not including 0.73.1, where archive extraction mishandles symlinks in a specifically crafted Zarf package. This allows symlinks to point outside the destination directory, enabling arbitrary file reads or writes on the host system processing the package. The vulnerability carries a CVSS v3.1 base score of 8.2 (AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N).

Exploitation requires local access to the system and user interaction, as an attacker must convince a user to process a malicious Zarf package with no privileges needed on the attacker's part. Upon extraction, the symlink traversal grants high-impact confidentiality and integrity violations, allowing arbitrary file read or write operations across the system, which could lead to data exfiltration, modification of critical files, or further privilege escalation in air-gapped Kubernetes environments.

The vulnerability has been patched in Zarf version 0.73.1. Administrators should immediately upgrade affected installations to this version or later to mitigate the issue. Additional details are available in the GitHub release notes at https://github.com/zarf-dev/zarf/releases/tag/v0.73.1 and the security advisory at https://github.com/zarf-dev/zarf/security/advisories/GHSA-hcm4-6hpj-vghm.

T1005 Data from Local System Collection

Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

T1565.001 Stored Data Manipulation Impact

Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.

Why these techniques?

Malicious Zarf package requires user processing (T1204.002); path traversal directly enables arbitrary local file reads (T1005) and stored data writes/manipulation (T1565.001).
