| CVE-2023-2033 | Type Confusion in Google Chromium V8 Engine Exploited in the Wild CVE-2023-2033 is a type confusion flaw (CWE-843) in Google's Chromium V8 JavaScript engine that a remote attacker can trigger by convincing a user to load a crafted HTML page. Successful exploitation could lead to heap corruption in the browser, potentially allowing the attacker to execute code in the context of the affected browser. Because V8 underpins the entire Chromium ecosystem, users of Google Chrome, Microsoft Edge, Opera, and any other Chromium-based browser or application are potentially affected. The flaw is already being exploited: CISA added it to the Known Exploited Vulnerabilities catalog on 2023-04-17, and EPSS assigns a 40.8% probability of exploitation within 30 days (99th percentile), though no public proof-of-concept is known and ransomware use is unknown. Do: Update Google Chrome and every other Chromium-based browser in use (Microsoft Edge, Opera, Brave, etc.) to the latest vendor-supplied stable release, per CISA's KEV required action to apply updates per vendor instructions. Verify installed browser versions across managed endpoints and treat unpatched Chromium builds as actively exploited given the KEV listing and high EPSS score. | 8.8 | 41% | KEV |
