A Cross-Site Scripting (XSS) vulnerability in Google Cloud Looker versions prior to 25.6.103, 25.12.65, 25.18.68, 26.0.66, 26.2.47, 26.4.36, 26.6.28, and 26.8.7 on Looker-hosted and Self-hosted allows an attacker to execute arbitrary JavaScript leading to administrative account takeover using a maliciously crafted URL.
