Executive Summary
The CVE‑2025‑58158 vulnerability affects Harness Open Source — specifically its Gitness component that powers Git LFS uploads. In versions prior to 3.3.0, improper upload-path sanitization enables an authenticated user to perform arbitrary file writes on the server. This critical flaw (CVSS 3.1 base score 8.8) poses a direct threat to the confidentiality, integrity, and availability of the server.OpenCVE+13NVD+13Cvetodo+13
1. Technical Breakdown
Affected Components
- Harness Gitness (Git LFS Server) used in developer platforms and CI/CD pipelines.
X (formerly Twitter)
Vulnerability Overview
- The upload API fails to properly sanitize file paths.
- As a result, authenticated users can craft payloads to write files anywhere on the host filesystem—even outside intended directories—leading to possible system compromise.Santa Fe Cyber+10NVD+10Cvetodo+10

2. Impact Analysis
Attack Scope
An attacker with minimal privileges and remote access can:
- Place backdoor files or scripts on the server.
- Overwrite critical project files or configs.
- Facilitate further malicious actions like RCE or privilege escalation.
Business Risk
Organizations using Harness for CI/CD, Git hosting, or artifacts are at risk of full platform compromise—leading to supply chain infiltration, data exfiltration, or infrastructure lockdown.
3. Mitigation & Solutions
Immediate Actions
- Update to version 3.3.0 or later of Harness (the patch fixes path sanitation flaws)Tenable®+8NVD+8Cvetodo+8Cvetodo+2Tenable®+2X (formerly Twitter)+3OpenCVE+3Tenable®+3X (formerly Twitter)+3Tenable®+3OpenCVE+3
- Restrict access to Gitness APIs to trusted internal networks behind VPN/firewalls.
Hardening Measures
- Enforce strict path validation and input sanitization.
- Apply the principle of least privilege for service accounts running Gitness.
- Monitor login and file upload patterns for anomalies.
