Cross-Site Scripting (XSS) in Looker's Extension Loader leading to Admin Account Compromise
An attacker with viewer permissions in Looker could craft a malicious URL that, when opened by a Looker admin, would execute an attacker-supplied script. Exploitation required at least one Looker extension installed on the instance. Looker-hosted and Self-hosted were found to be vulnerable. This issue has already been mitigated for Looker-hosted instances. No user action is required for these. Self-hosted instances must be upgraded as soon as possible. This vulnerability has been patched in all supported versions of Self-hosted. The versions below have all been updated to protect from this vulnerability. You can download these versions at the Looker download page https://download.looker.com/ : * 24.18.201+ * 25.0.79+ * 25.6.66+ * 25.12.7+ * 25.16.0+ * 25.18.0+ * 25.20.0+
