CVE-2023-0133Network attack vector

Permission delegation bypass via crafted HTML

Published Jan 10, 2023 · Updated Mar 20, 2025

Incorrect authorization in Google Chrome on Android before 109.0.5414.74 allows remote attackers to bypass main-origin permission delegation. A crafted HTML page reaches the permission-prompt path, which delegates permission without correctly enforcing the main origin’s authorization context. A user must open attacker-controlled content; public records do not identify the responsible function or disclose finer implementation details.
