Short for Cross Site Scripting. A type of web based security vulnerability using client side scripts such as Javascript.

XSS takes place as a consequence of improper input sanitization. When the input provided by the user is not properly sanitized, an ill willed user may insert scripting code into a web page, which in turn will be executed by the visitor's browser. There are 2 kinds of XSS attacks: stored or reflected. Stored would mean that the injected code is permanently stored in the page, such as in a comment. Reflected would mean that it only appears once when the payload (i.e. the malicious input) is part of the request, maybe in parameters or cookies.
We have discovered an XSS vulnerability in the user profile view.

Word of the Day on October 28, 2026
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
