Permission bypass via undisclosed prompt implementation

Published May 2, 2023 · Updated Feb 13, 2025

Inappropriate prompt implementation in Google Chrome before 113.0.5672.63 allows remote attackers to bypass permission restrictions via crafted HTML. Google identifies the affected locus only as Prompts and has not published the incorrect operation performed on untrusted page content. A victim must load attacker-controlled HTML, after which the page can evade a browser permission restriction; no broader impact is documented.
