CVE-2026-7596Public exploitNetwork attack vector

Stored XSS via unescaped slide JSON fields

Published May 1, 2026 · Updated May 1, 2026

Stored XSS in Next Level Builders UI UX Pro Max 2.5.0 and earlier allows attackers to inject script into generated slide decks. Seven slide-generator functions interpolate JSON values through Python f-strings into HTML content and href attributes without entity encoding or URL-scheme checks. A user must open the generated HTML in a browser, where injected script can alter displayed content or perform actions in that document context.
