Preliminary research
What's in a tag name? JavaScript, apparently
AI-collected research leads through 3 November 2026, including a November–October–September missed-article review and a targeted multilingual search alongside earlier community-source sweeps. Unranked, incomplete, not community-vetted, and subject to change.
JavaScript hidden in an HTML tag name becomes a payload source when an executable handler reads and transforms that name. The article develops a reusable XSS construction from browser parsing and string behavior; its demonstrated primitive does not by itself establish a bypass of a deployed filter.
