Overview

About vulnerability

jsoup is a Java library for working with real-world HTML. From 1.14.3 until 1.23.1, jsoup’s HTML parser could incorrectly handle a malformed tag name ending in a control character, causing the tag to acquire the parsing behavior of a different element. When a custom Safelist permits certain raw-text elements, this misparsing can cause content that should remain inert text to be emitted as active markup after serialization, potentially resulting in cross-site scripting. jsoup’s built-in Safelists are not affected. This issue is fixed in version 1.23.1.
