Description
A Looker user with a Developer role could create a database connection using IBM DB2 driver and, by manipulating LookML, cause Looker to execute a malicious command, due to inadequate filtering of the driver's parameters.
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.
