Cross-site Scripting Vulnerability in Dashbitco LazyHTML Product

CVE-2026-92106

What is CVE-2026-92106?

The vulnerability in Dashbitco's LazyHTML arises from improper handling of input during web page generation, specifically within SVG and MathML content. When an attacker supplies compromised HTML, the affected versions of LazyHTML fail to appropriately escape elements' text. This misconfiguration allows for the execution of untrusted scripts as part of the markup. Attackers can exploit this by inserting encoded markup, which is parsed and serialized incorrectly, resulting in live markup that can execute arbitrary code on the user's browser. Applications utilizing LazyHTML to parse untrusted HTML should implement stringent validations to safeguard against these types of attacks.
