CVE-2026-19727Network attack vector

Cross-site scripting via unsanitized HTML attributes

Published Sep 4, 2026 · Updated Sep 4, 2026

Cross-site scripting in Yordam Library Automation System before 22.2 allows remote attackers to run script through crafted HTML attribute input. The HTML-generation path places user-controlled input into an HTML attribute without adequate neutralization; the affected page and input field are undisclosed. No authentication is required, but a user must interact with the generated content; exploitation can expose or alter data in that user's browser context without interrupting service.
