Authenticated script execution via HTML injection

Published Dec 26, 2025 · Updated Dec 26, 2025

HTML injection in IBM Aspera Faspex 5 5.0.0 through 5.0.14.1 allows remote authenticated users to run scripts when a victim views crafted content. IBM has not published the affected field, request path, or sanitization operation that accepts and later renders the malicious markup. Exploitation requires an authenticated injector and a separate victim view; the script runs in the Faspex site context and can read or alter browser-accessible data.
