CVE-2018-6066

23
FAUCET Score

CVE-2018-6066 describes a cross-origin data leakage vulnerability in Google Chrome prior to version 65.0.3325.146, specifically affecting the Blink rendering engine due to a lack of CORS checking by ResourceFetcher/ResourceLoader. This medium-severity vulnerability (CVSS 6.5) could allow a remote attacker to steal sensitive cross-origin data by enticing a user to visit a specially crafted HTML page. While the vulnerability has a high confidentiality impact, there is no evidence of active exploitation, nor are there publicly available exploit modules in Metasploit or ExploitDB. Despite its age, it garnered some community discussion and media coverage at the time of disclosure.
