CVE-2023-36822Public exploitNetwork attack vector

Authenticated file deletion via unsanitized plugin name

Published Jul 5, 2023 · Updated Oct 24, 2024

Path traversal in Louis Lam's Uptime Kuma before 1.22.1 allows remote authenticated users to delete server files through plugin installation. The installPlugin path in server/plugins-manager.js concatenates an unchecked plugin name with the plugin directory and passes the result to recursive fs.rmSync. Login access to the still-exposed plugin API is required; deletion can crash Uptime Kuma or render the host unavailable through data loss.
