Summary
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+
Risk Assessment
An attacker with Developer permission can execute arbitrary shell commands, potentially leading to full system compromise and data access.
Recommendation
For self-hosted instances, immediately upgrade Looker to one of the following versions: 24.12.100+, 24.18.192+, 25.0.69+, 25.6.57+, 25.8.39+, or 25.10.22+. Looker-hosted instances require no action.
