Script execution via unfiltered image markup
Published Jul 30, 2025 · Updated Jul 30, 2025
Cross-site scripting in playground.electronhub.ai 1.1.9 and earlier allows remote attackers to execute scripts via crafted input. The playground accepts image markup carrying an onerror handler without filtering the input, so a user's browser executes the handler. Exploitation requires a user to submit or render the crafted input; the public proof of concept demonstrates JavaScript execution in that browser context.
