Lychee is a self-hosted photo-management and gallery. I am using the Lychee application for my personal usage (mostly sharing pictures with the family).

The application has been greatly improved since the last update of my instance. I fired up a docker and start taking a look at the application for new features. It was not long before I found a few XSS, one of them could allow unauthenticated users to to gain logged access to the platform by creating a new account.

I reported the issues to the project and we created a Github Security Advisory: https://github.com/LycheeOrg/Lychee-front/security/advisories/GHSA-cr79-38hg-27gv.

This is a writeup about a retired HacktheBox machine: Book This box is classified as a medium machine published on February the 22th 2020 by MrR3boot. It involves some XSS, an SQL truncation injection and a CVE on logrotate.
