CVE-2026-28499
LeafKit's HTML escaping may be skipped for Collection values, enabling XSS
Summary
LeafKit's HTML escaping may be skipped for Collection values, enabling XSS
Original description
The description as published by the source.
LeafKit is a templating language with Swift-inspired syntax. Prior to version 1.14.2, HTML escaping doesn't work correctly when a template prints a collection (Array / Dictionary) via #(value). This can result in XSS, allowing potentially untrusted input to be rendered unescaped. Version 1.14.2 fixes the issue.
