  "title": "incus: Incus is a system container and virtual machine manager",
  "description": "Incus is a system container and virtual machine manager. Prior to version 6.23.0, the web server spawned by \u0060incus webui\u0060 incorrectly validates the authentication token such that an invalid value will be accepted. \u0060incus webui\u0060 runs a local web server on a random localhost port. For authentication, it provides the user with a URL containing an authentication token. When accessed with that token, Incus creates a cookie persisting that token without needing to include it in subsequent HTTP requests. While the Incus client correctly validates the value of the cookie, it does not correctly validate the token when passed int the URL. This allows for an attacker able to locate and talk to the temporary web server on localhost to have as much access to Incus as the user who ran \u0060incus webui\u0060. This can lead to privilege escalation by another local user or an access to the user\u0027s Incus instances and possibly system resources by a remote attack able to trick the local user into interacting with the Incus UI web server. Version 6.23.0 patches the issue.",
