## Summary

The WIT SynApps Runtime web application is affected by a reflected cross-site scripting flaw that can be triggered without logging in. An attacker who gets a user to open a specially crafted link could run arbitrary JavaScript in the victim's browser, potentially stealing credentials, altering the login process, reading data visible in the browser, and making same-origin requests to internal controller endpoints.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- WIT SynApps Runtime: through 1.4.11

## Description

WIT SynApps Runtime through 1.4.11 contains a pre-authentication reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject and execute arbitrary JavaScript by submitting a crafted LINK query parameter to the /System/Session-1 endpoint. Attackers can exploit this flaw to harvest credentials, manipulate the login flow, access browser-visible data, and perform same-origin requests to controller endpoints, including an origin-switch primitive against the internal controller in Cloud RIA scenarios.
