CVE-2022-24071Network attack vector

Internal API control via privileged extension misuse

Published Jan 28, 2022 · Updated Aug 3, 2024

Privilege-boundary bypass in NAVER Whale Browser before 3.12.129.46 allows remote attackers to control internal browser APIs. The built-in extension crosses the renderer privilege boundary and exposes browser-internal APIs, but NAVER has not published the faulty call or input path. Exploitation requires a user to interact with attacker-controlled content; the bounded result is unauthorized modification through internal browser APIs, not demonstrated host code execution.
