CVE-2020-6490

14
FAUCET Score

CVE-2020-6490 describes an insufficient data validation vulnerability in the loader component of Google Chrome prior to version 83.0.4103.61, also affecting Debian, Fedora, and OpenSUSE. This medium-severity vulnerability (CVSS 4.3) could allow a remote attacker, who has already achieved disk write access, to leak cross-origin data through a specially crafted HTML page, requiring user interaction. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or inclusion in CISA's KEV catalog. Despite its low EPSS score and FAUCET risk, it has garnered some community discussion and media coverage.
