CVE-2022-36778

Stored script execution via worker nickname

Published Sep 13, 2022 · Updated Sep 17, 2024

Stored cross-site scripting in Synel eHarmony before 11 allows remote authenticated users to inject script through a worker nickname. eHarmony stores HTML or JavaScript supplied in the Workers worker-nickname field and renders it without neutralizing executable content. Low-privileged worker-editing access is required, and rendering the stored nickname exposes data and actions available to the affected browser session.
