CVE-2018-6103

22
FAUCET Score

CVE-2018-6103 describes a medium-severity vulnerability in Google Chrome prior to version 66.0.3359.117, where a stagnant permission prompt could be bypassed by a remote attacker using a crafted HTML page. This allowed for unauthorized modification of user settings or data (CVSS 6.5, I:H) without requiring user interaction beyond visiting the malicious page. While the vulnerability affects Google Chrome and related distributions like Debian and Red Hat, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage beyond a single mention.
