How severe is CVE-2026-41211?

CVE-2026-41211 has a CVSS score of 10/10, rated CRITICAL. Immediate patching is strongly recommended.

Which products are affected by CVE-2026-41211?

Affected package information for CVE-2026-41211 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2026-41211?

Apply the voidzero vite\+ security patch or hotfix for CVE-2026-41211 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2026-41211 across my infrastructure?

Inventory every voidzero vite\+ deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2026-41211 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2026-41211?

O3 detects and blocks CVE-2026-41211 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2026-41211 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-41211 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-2026-41211?

CVE-2026-41211 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 23th 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-2026-41211?

CVE-2026-41211 is classified as Path Traversal (CWE-22). This weakness type 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.

Which products and versions are affected by CVE-2026-41211?

CVE-2026-41211 affects voidzero vite\+. Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2026-41211 published, and has it been updated?

CVE-2026-41211 was published on April 23, 2026 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

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.

Detect
Inventory every voidzero vite\+ deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the voidzero vite\+ security patch or hotfix for CVE-2026-41211 on the affected version, following the vendor advisory for your exact build.
Workarounds
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
