26
FAUCET Score

CVE-2020-6477 describes an inappropriate implementation vulnerability in the Google Chrome installer on macOS, affecting versions prior to 83.0.4103.61, and also impacting products from Apple, Fedora, and openSUSE. This local privilege escalation flaw, rated 7.8 HIGH, allows an attacker with local access to execute arbitrary code with elevated privileges through a crafted file. While the vulnerability has a high severity and potential for significant impact (confidentiality, integrity, availability), there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or inclusion in CISA's KEV catalog. Despite limited community discussion, it garnered media attention upon Chrome 83's release.
