Summary

CVE-2026-41211 is a high-severity Path Traversal (CWE-22) vulnerability in Voidzero Vite\+. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 22.7th 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-2026-41211 is a path traversal vulnerability (CWE-22) in Vite+, a unified toolchain and entry point for web development. In versions prior to 0.1.17, the `downloadPackageManager()` function accepts an untrusted `version` string and incorporates it directly into filesystem paths without sanitization. This allows attackers to include `../` path traversal sequences or absolute paths, enabling escape from the intended `VP_HOME/package_manager/<pm>/` cache root.

The vulnerability has a CVSS v3.1 base score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H), indicating critical severity with network accessibility, low attack complexity, no privileges or user interaction required, and scope change. Remote unauthenticated attackers who can invoke `downloadPackageManager()`—such as through malicious inputs in web development workflows—can exploit it to delete, replace, or populate arbitrary directories outside the cache root, potentially leading to filesystem disruption, persistence, or supply chain compromise.

Version 0.1.17 of Vite+ patches the issue by addressing the unsafe path handling. Security practitioners should upgrade to this version or later, as detailed in the GitHub Security Advisory at https://github.com/voidzero-dev/vite-plus/security/advisories/GHSA-33r3-4whc-44c2.

Vulnerability details

Vite+ is a unified toolchain and entry point for web development. Prior to version 0.1.17, `downloadPackageManager()` accepts an untrusted `version` string and uses it directly in filesystem paths. A caller can supply `../` segments or an absolute path to escape…

the `VP_HOME/package_manager/<pm>/` cache root and make Vite+ delete, replace, and populate directories outside the intended cache location. Version 0.1.17 contains a patch.

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1195 Supply Chain Compromise Initial Access

Adversaries may manipulate products or product delivery mechanisms prior to receipt by a final consumer for the purpose of data or system compromise.

Why these techniques?

Path traversal enables remote unauthenticated exploitation of the exposed toolchain (T1190) and facilitates supply chain compromise via arbitrary file writes/deletes outside the cache directory (T1195).
