Vulnerability from fkie_nvd - Published: 2025-11-24 10:15 - Updated: 2026-06-17 08:32
Severity
Summary
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+
