25
FAUCET Score

CVE-2012-5851 describes a cross-site scripting (XSS) bypass vulnerability in WebKit's XSS Auditor, affecting Google Chrome through version 22 and Safari 5.1.7. This flaw allows remote attackers to circumvent XSS protection mechanisms by crafting specific strings that are not properly sanitized across all output contexts. With a CVSS score of 4.3, it is a medium-severity vulnerability requiring moderate attack complexity, potentially leading to information disclosure (integrity impact of partial). While there is no evidence of active exploitation or Metasploit modules, an ExploitDB entry exists, and community discussion and media coverage are minimal.
