CVE-2026-50700Network attack vector

Stored XSS via unneutralized avatar rendering

Published Jun 24, 2026 · Updated Jun 24, 2026

Stored XSS in frappe.get_avatar in Frappe Framework 17.0.0-dev allows remote authenticated users to run scripts via crafted avatar data. The function places user-controlled avatar content into image rendering without neutralizing executable markup, although the public record does not identify the exact parameter or output sink. Exploitation requires high-privileged access and a user to view the rendered avatar; the script then runs in that viewer’s browser context.
