# CVE-2026-118682: ClashMi through 1.0.32.1801 Disabled TLS Certificate Validation Enables Update MITM

- Also known as: EUVD-2026-112489, GHSA-WVPM-52PR-RWW8
- Severity: CVSS 7.7 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- Known exploited (CISA KEV): no
- Published: 2026-10-28 · Updated: 2026-10-28

## Summary

ClashMi, a proxy client application for Windows, is affected. Because it turns off TLS certificate checks in its update mechanism, an attacker positioned on the network path, such as someone running the user's proxy node, could impersonate the update server and deliver a malicious installer that runs arbitrary code on the user's computer.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- KaringX clashmi: through 1.0.32.1801

## Description

KaringX ClashMi through 1.0.32.1801 disables TLS certificate validation by default in the HttpUtils helper, allowing attackers to intercept HTTPS traffic by presenting any certificate. Attackers operating the user's proxy node can serve a forged update manifest omitting sha256 to deliver a malicious installer, achieving code execution when the update runs.
