CVE-2023-0141Network attack vector

Cross-origin data disclosure via insufficient CORS enforcement

Published Jan 10, 2023 · Updated Mar 20, 2025

Insufficient CORS policy enforcement in Google Chrome before 109.0.5414.74 allows remote attackers to read cross-origin data via crafted HTML. The public record does not identify the affected CORS code path or explain which policy check fails before cross-origin response data is exposed. Exploitation requires a user to open attacker-controlled HTML, and the documented consequence is limited to unintended cross-origin data disclosure.
