CVE-2018-25058Network attack vector

Opener-tab redirection via missing noopener isolation

Published Dec 29, 2022 · Updated Aug 5, 2024

Reverse tabnabbing in Jason Mayes Twitter Post Fetcher before 18.0.0 allows remote attackers to redirect an opener tab via rendered links. The link renderer assigns target="_blank" to fetched and interaction anchors without rel="noopener", exposing window.opener to the destination page. Exploitation requires a user to open an attacker-controlled link; script in the new tab can change the original tab's location, enabling phishing or unwanted navigation.
