Description
A Command Injection vulnerability, resulting from improper file path sanitization (Directory Traversal) in Looker allows an attacker with Developer permission to execute arbitrary shell commands when a user is deleted on the host system. 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/ : * 24.12.100+ * 24.18.192+ * 25.0.69+ * 25.6.57+ * 25.8.39+ * 25.10.22+

Executive Summary

This vulnerability is a Command Injection issue caused by improper file path sanitization (Directory Traversal) in Looker. It allows an attacker who has Developer permission to execute arbitrary shell commands on the host system when a user is deleted. This affects both Looker-hosted and Self-hosted instances, though the issue has been mitigated for Looker-hosted instances.

Impact Analysis

An attacker with Developer permission could exploit this vulnerability to execute arbitrary shell commands on the host system, potentially leading to unauthorized system access, data compromise, or disruption of services. This could result in significant security risks for affected Self-hosted Looker instances if not patched.

Mitigation Strategies

For Self-hosted Looker instances, immediately upgrade to one of the patched versions listed: 24.12.100+, 24.18.192+, 25.0.69+, 25.6.57+, 25.8.39+, or 25.10.22+. Looker-hosted instances have already been mitigated and require no user action.
