Exploitation required at least one Looker extension installed on the instance.\n\nLooker-hosted and Self-hosted were found to be vulnerable.\nThis issue has already been mitigated for Looker-hosted instances. No user action is required for these.\n\n\nSelf-hosted instances must be upgraded as soon as possible. This vulnerability has been patched in all supported versions of Self-hosted.\nThe 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+\n  *  25.0.79+\n  *  25.6.66+\n  *  25.12.7+\n  *  25.16.0+\n  *  25.18.0+\n  *  25.20.0+",
