Short explanation
NAVER Whale Browser versions prior to 5.39.412.57 allow bypass of the iframe sandbox in a dual‑tab environment, potentially enabling malicious content execution. Patch status could not be verified in official sources.
Bypassing the iframe sandbox lets attackers run code in an isolated frame, facilitating data theft or other malicious actions.
What should be done?
- Monitor NAVER security advisories
- Apply patches promptly when released
- Enforce stricter sandbox attributes on iframes
- Limit use of isolated content via browser security settings
- Consider alternative hardened browsers
