Stored script execution via unneutralized redirect message
Published Jan 23, 2026 · Updated Jan 23, 2026
Stored cross-site scripting in Jamie Sage Thread Redirect 0.2.1 allows remote attackers to run scripts in viewers' browsers. The redirect-thread custom message accepts an SVG onload handler and later renders it on the redirect screen without neutralizing executable markup. An attacker must be allowed to create a redirecting thread, and script execution occurs when another user opens that thread.
