CVE-2020-6443 is a security vulnerability discovered in Google Chrome prior to version 81.0.4044.92. The vulnerability involves insufficient data validation in developer tools that allowed a remote attacker to execute arbitrary code via a crafted HTML page, provided they could convince a user to use devtools. The vulnerability was reported by @lovasoa (Ophir LOJKINE) on January 8, 2020, and was fixed in Chrome version 81.0.4044.92 (Chrome Release).

The vulnerability is classified as a Low severity issue with a CVSS v3.1 Base Score of 8.8 HIGH (Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). The vulnerability stems from insufficient validation of data in the Chrome developer tools, which could lead to arbitrary code execution. The weakness is categorized under CWE-345 (Insufficient Verification of Data Authenticity) (NVD).

If successfully exploited, this vulnerability could allow an attacker to execute arbitrary code within the context of the browser's developer tools. This could potentially lead to unauthorized access to sensitive information, manipulation of browser data, or execution of malicious code (Debian Advisory).

The primary mitigation is to update Google Chrome to version 81.0.4044.92 or later. The vulnerability has been fixed in this version and all subsequent releases. Multiple Linux distributions have also released security updates to address this vulnerability, including Debian, Fedora, and OpenSUSE (Chrome Release).
