CVE-2019-5773

CVE-2019-5773 is a medium-severity vulnerability in Google Chrome versions prior to 72.0.3626.81, specifically affecting its IndexedDB implementation, and also impacting Debian, Fedora, and Red Hat distributions. It stems from insufficient origin validation, allowing a remote attacker who has compromised the renderer process to bypass the same-origin policy through a crafted HTML page. The vulnerability has a CVSS score of 6.5, indicating a network-based attack with low complexity requiring user interaction, and could lead to high integrity impacts. There is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage, suggesting it is not a widely targeted vulnerability.
