CVE-2026-76033Source published Source updated
Inappropriate implementation in CORS in Google Chrome prior to 151.0.7922.169 allowed a remote attacker who had compromised the renderer process to bypass site isolation via a crafted HTML page. (Chromium security severity: High) A flaw was found in Google Chrome's handling of Cross-Origin Resource Sharing (CORS). This could allow the attacker to bypass site isolation, a security feature designed to prevent malicious websites from accessing data from other websites, potentially leading to unauthorized data access. This could lead to unauthorized access to sensitive data from other websites, significantly undermining a core browser security boundary. Red Hat severity: Important — CVSS 8.7 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N). Weakness: CWE-653.
