CVE-2018-6089 is a medium-severity vulnerability in Google Chrome (prior to version 66.0.3359.117) that allowed limited cross-origin data leakage. This flaw stemmed from a lack of Cross-Origin Resource Sharing (CORS) checks after a Service Worker redirected to a cross-origin PDF, enabling a remote attacker to exfiltrate data via a specially crafted HTML page. The vulnerability has a CVSS score of 6.5, indicating a network-based attack requiring user interaction, with high confidentiality impact. While not listed in CISA's KEV catalog, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), and community discussion and media coverage are minimal, suggesting limited active exploitation.
