hi, i'm daniel. i'm a 16-year-old high school senior. in my free time, i hack billion dollar companies and build cool stuff.

about a month ago, a couple of friends and I found serious critical vulnerabilities on Mintlify, an AI documentation platform used by some of the top companies in the world.

i found a critical cross-site scripting vulnerability that, if abused, would let an attacker to inject malicious scripts into the documentation of numerous companies and steal credentials from users with a single link open.

(go read my friends' writeups (after this one))

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

Unicode XSS via Combining Characters

Most application security practitioners are familiar with Unicode XSS, which typically arises from the Unicode character fullwidth-less-than-sign. It’s not a common vulnerability but does occasionally appear in applications that otherwise have good XSS protection. In this blog I describe another variant of Unicode XSS that I have identified, using combining characters. I’ve not observed this in the wild, so it’s primarily of theoretical concern. But the scenario is not entirely implausible and I’ve not otherwise seen this technique discussed, so I hope this is useful.

Recap of Unicode XSS

Lab: https://4t64ubva.xssy.uk/

A quick investigation of the lab shows that it is echoing the name parameter, and performing HTML escaping:
