In versions prior to 3.3.12, due to vulnerabilities in TeXLive and obscure LaTeX syntax that allowed circumventing Indico's LaTeX sanitizer, it is possible to use specially-crafted LaTeX snippets which can read local files or execute code with the privileges of the user running Indico on the server. Note that if server-side LaTeX rendering is not in use (ie `XELATEX_PATH` was not set in `indico.conf`), this vulnerability does not apply. It is recommended to update to Indico 3.3.12 as soon as possible. It is also strongly recommended to enable the containerized LaTeX renderer (using `podman`), which isolates it from the rest of the system. As a workaround, remove the `XELATEX_PATH` setting from `indico.conf` (or comment it out or set it to `None`) and restart the `indico-uwsgi` and `indico-celery` services to disable LaTeX functionality."}, {"lang": "es", "value": "Indico es un sistema de gesti\u00f3n de eventos que utiliza Flask-Multipass, un sistema de autenticaci\u00f3n multi-backend para Flask.
