Very high risk99th percentile - higher than 99% of all known CVEs
Summary
Cachet, an open-source status page system, prior to the 2.4 branch contains a template functionality that allows users to execute arbitrary code on the server due to bad filtration and an old Twig version. Commit 6fb043e109d2a262ce3974e863c54e9e5f5e0587 of the 2.4 branch contains a patch for this issue.
Risk Assessment
A user able to create templates can execute arbitrary code on the server, leading to full compromise of the application and host. The risk is high in environments with multiple users having template permissions.
Recommendation
Upgrade Cachet to the 2.4 branch containing commit 6fb043e109d2a262ce3974e863c54e9e5f5e0587 or later. Restrict template creation permissions to trusted administrators.
