Credential theft via reverse tabnabbing
Published Jul 9, 2025 · Updated Jul 9, 2025
Reverse-tabnabbing security bypass in ASUSTOR DataSync Center allows attackers to steal credentials by changing a previously opened browser tab. ASUSTOR identifies reverse tabnabbing but has not published the affected page or whether it omits opener isolation on an external link. Exploitation requires high privileges, a prepared condition, and passive user interaction; the reported effect is deceptive tab content with credential-theft risk.
