DOM XSS via redirect GET parameter

Published Aug 3, 2023 · Updated Oct 9, 2024

DOM-based XSS in Palantir Foundry Frontend before 6.225.0 allows remote attackers to execute script via a crafted redirect parameter. The Developer mode dashboard fails to neutralize dangerous URI content from the redirect GET parameter before client-side DOM use. The attack requires user interaction and a separate bypass of Foundry’s CSP; the published impact is limited to confidentiality loss.
