### Summary Installation of a maliciously crafted plugin allows for remote code execution by an authenticated attacker. ### Details Uptime Kuma allows authenticated users to install plugins from an official list of plugins. This feature is currently disabled in the web interface, but the corresponding API endpoints are still available after login. After downloading a plugin, it's installed by calling `npm install` in the installation directory of the plugin: https://github.com/louislam/uptime-kuma/blob/8c60e902e1c76ecbbd1b0423b07ce615341cb850/server/plugins-manager.js#L210-L216 Because the plugin is not validated against the official list of plugins or installed with `npm install --ignore-scripts`, a maliciously crafted plugin taking advantage of [npm scripts](https://docs.npmjs.com/cli/v9/using-npm/scripts) can gain remote code execution. ### PoC In the PoC below, the plugin at https://github.com/n-thumann/npm-install-script-poc will be installed. It only consists of an empty `inde...
### Summary A path traversal vulnerability via the plugin repository name allows an authenticated attacker to delete files on the server leading to unavailability and potentially data loss. ### Details Uptime Kuma allows authenticated users to install plugins from an official list of plugins. This feature is currently disabled in the web interface, but the corresponding API endpoints are still available after login. Before a plugin is downloaded, the plugin installation directory is checked for existence. If it exists, it's removed before the plugin installation. Because the plugin is not validated against the official list of plugins or sanitized, the check for existence and the removal of the plugin installation directory are prone to path traversal. ### Impact This vulnerability allows an authenticated attacker to delete files from the server Uptime Kuma is running on. Depending on which files are deleted, Uptime Kuma or the whole system may become unavailable due to data loss.

An attacker could possibly use this issue to pollute the prototype of the returned object, setting arbitrary or unexpected keys, and cause a denial of service, allow unintended access to network services or have other unspecified impact, depending on the application's use of the module.
