CVE-2026-15091Network attack vector

Script execution via undisclosed web-page input

Published Jul 17, 2026 · Updated Jul 17, 2026

Cross-site scripting in IBM Engineering AI Hub 1.0.0, 1.1.0, and 1.2.0 allows remote attackers to execute scripts in a user's browser. IBM identifies improper neutralization during web page generation but does not disclose the affected endpoint, input field, rendering path, or sanitization failure. Exploitation requires no privileges but does require user interaction; successful attacks can read or alter browser-accessible data in the affected user's security context.
