Persistent JavaScript via fragmented administrative fields
Published May 20, 2026 · Updated May 20, 2026
Stored XSS in Taiko AG1000-01A SMS Alert Gateway Rev 7.3, Rev 8, and UM-AG1000_R7.2 allows remote authenticated users to run persistent JavaScript. The interface stores fragments from multiple administrative fields and renders them in index.zhtml without neutralization, while comments and template literals reassemble executable code. Administrative access is required to store the payload, and the code runs only when an administrative dashboard view loads it.
