Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

serialize-javascript 7.1.1 (>=7.1.1, <7.1.2) fails to escape a closing script tag in serialized function bodies, so output embedded in a script element can end early and inject HTML. An attacker who can supply a crafted function body that gets serialized into a page can run script in the page's origin, though data values are not affected. Upgrade to 7.1.2, the fixed version.
