CVE-2026-23497Network attack vector

Stored XSS via unsanitized image filename

Published Jan 14, 2026 · Updated Jan 14, 2026

Stored XSS in Frappe Learning 2.44.0 and earlier allows remote attackers to execute JavaScript through crafted image filenames. The course and job upload flows stored uploader-returned image URLs without neutralizing filename markup before course and jobs pages rendered them. Execution requires another user to view a page containing the stored filename and affects that viewer's browser context.
