Authenticated script execution via unsanitized onerror argument
Published Jun 22, 2024 · Updated Aug 1, 2024
Cross-site scripting in SkyCaiji 2.0 through 2.8 allows remote authenticated users to inject script through the Task Handler onerror argument. The handler accepts attacker-controlled onerror content and renders it as executable browser markup without neutralization. High-privilege Task Handler access and user interaction are required; exploitation runs script in the viewing user's browser context.
