+# Offensive Umbraco Part 4: Let’s Get Pasted
 
-reveal.js is an open source HTML presentation framework. It enables anyone with a web browser to create fully featured and beautiful presentations for free. [Check out the live demo](https://revealjs.com/).
+Analysis of a path traversal vulnerability I discovered in Umbraco, how it was patched, and how developers can prevent similar vulnerabilities in their own .NET code.
 
-The framework comes with a broad range of features including [nested slides](https://revealjs.com/vertical-slides/), [Markdown support](https://revealjs.com/markdown/), [Auto-Animate](https://revealjs.com/auto-animate/), [PDF export](https://revealjs.com/pdf-export/), [speaker notes](https://revealjs.com/speaker-view/), [LaTeX support](https://revealjs.com/math/), [syntax highlighted code](https://revealjs.com/code/) and much more.
+Delivered in April 2024 at the Edinburgh Umbraco Users Group meetup.
