CVE-2022-34768

Stored script execution via unsanitized worker nickname

Published Aug 5, 2022 · Updated Jun 2, 2026

Stored XSS in Synel eHarmony 11 allows remote authenticated users on an adjacent network to execute script via a worker nickname. The worker-nickname input stores HTML and JavaScript and later renders the saved value without neutralizing executable markup. Low-privileged access is required, and the injected code runs in the web context that displays the saved nickname, exposing data and actions available there.
