Descripción
*** Pendiente de traducción *** When a post is published, Postiz treats a media path that is not a web address as a file on the server&#39;s disk, but it does not check that the file lies inside the upload directory. A registered user can store a crafted media path with a post, get it past the checks that normally restrict it, and have the publishing worker read an arbitrary file and send it as an attachment to a Discord server the user controls.<br />
<br />
The same unconfined reads can be reached through two further routes. One tells the caller whether a file exists and can exhaust the backend&#39;s memory, the other delivers the file the same way as the main route. Self-registration is open by default, so the attacker needs no existing account.
