CVE-2026-3096
Reverse Tabnabbing via New Tab Navigation in Multiple WSO2 Products Allows Phishing and Credential Theft
Description
The product's web portals allow external links to be opened in a new browser tab. In certain configurations, the originating window retains access to the newly opened page, allowing interaction between the two browser contexts when navigating to external destinations. This vulnerability could allow an attacker to manipulate the original trusted application window after a user clicks a malicious external link. This manipulation can lead to users being redirected to phishing pages, enabling credential theft, or facilitating other unauthorized actions within the context of the trusted site.
