User redirection via reverse tabnapping in Project Shortcuts
Published Aug 25, 2021 · Updated Oct 11, 2024
Reverse tabnapping in Atlassian Jira Server and Data Center allows remote attackers to redirect users through malicious Project Shortcuts. Atlassian identifies the Project Shortcuts feature but has not published the faulty link-handling operation that enables the redirect. Exploitation requires high-privileged Jira access to plant the shortcut and user interaction to follow it, exposing the new page to malicious navigation.
