How severe is CVE-2025-58158?

CVE-2025-58158 has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2025-58158?

CVE-2025-58158 affects the following packages: github.com/harness/gitness (Go), github.com/harness/gitness (Go). Ecosystems affected: Go.

How do I fix CVE-2025-58158?

Update github.com/harness/gitness to 3.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-58158 is resolved across your whole dependency graph.

How do I detect CVE-2025-58158 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/harness/gitness. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2025-58158 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2025-58158?

O3 pinpoints whether CVE-2025-58158 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2025-58158 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-58158 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-58158?

CVE-2025-58158 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 36th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-58158?

CVE-2025-58158 is classified as Path Traversal (CWE-22), CWE-73 (CWE-73). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2025-58158 published, and has it been updated?

CVE-2025-58158 was published on August 29, 2025 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Harness Open Source is an end-to-end developer platform with Source Control Management, CI/CD Pipelines, Hosted Developer Environments, and Artifact Registries. Prior to version 3.3.0, Open Source Harness git LFS server (Gitness) exposes api to retrieve and upload files via git LFS. Implementation of upload git LFS file api is vulnerable to arbitrary file write. Due to improper sanitization for upload path, a malicious authenticated user who has access to Harness Gitness server api can use a crafted upload request to write arbitrary file to any location on file system, may even compromise the server. Users using git LFS are vulnerable. This issue has been patched in version 3.3.0.
