Description
CVE-2024-53382
Prism (aka PrismJS) through 1.29.0 allows DOM Clobbering (with resultant XSS for untrusted input that contains HTML but does not directly contain JavaScript), because document.currentScript lookup can be shadowed by attacker-injected HTML elements.

Research direction
Start by reading the CVE-2024-53382 report and tracing Prism 1.29's document.currentScript lookup, focusing on how attacker-injected HTML can shadow it. Done means the reported DOM Clobbering path no longer produces the described XSS behavior for untrusted HTML, with regression coverage added where appropriate.
