Vulnerability from cvelistv5 – Published: 2026-09-10 20:40 – Updated: 2026-09-10 20:40

Title

Reverse Tabnabbing via New Tab Navigation in Multiple WSO2 Products Allows Phishing and Credential Theft

Summary

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.
