CVE-2026-81731
MediumCVSS 5.4Exploitation Probability (EPSS)
Low risk7th percentile - higher than 7% of all known CVEs
Summary
Frappe 15.11.0 through 16.32.0 stores and renders workspace card descriptions without XSS filtering. The description field is marked with ignore_xss_filter, and _sanitize_content() skips such fields, so the value is stored as submitted. It is then interpolated into a Bootstrap popover with html: true, allowing a user with the Workspace Manager role to execute arbitrary markup in the sessions of other desk users.
Risk Assessment
An attacker can steal session tokens and perform authenticated requests as the victim, including higher-privileged users, leading to unauthorized access and data integrity compromise.
Recommendation
Apply the fix from the development branch or upgrade to a patched release when available. Temporarily restrict Workspace Manager role assignments and monitor activity.
Original NVD description (English source)
Frappe 15.11.0 through 16.32.0 stores and renders the workspace card description without XSS filtering. The description field of the Workspace Link doctype is declared with "ignore_xss_filter": 1 in frappe/desk/doctype/workspace_link/workspace_link.json, and _sanitize_content() in frappe/model/base_document.py skips any field carrying that flag, so the value is stored exactly as submitted. frappe.desk.desktop.get_desktop_page returns it unchanged, and LinksWidget.set_body() in frappe/public/js/frappe/widgets/links_widget.js interpolates it into a Bootstrap popover created with html: true, by way of the __() translation helper, which performs no HTML escaping. A user holding the Workspace Manager role can therefore place arbitrary markup in a public workspace's card description and have it execute in the session of any desk user who opens that workspace and hovers the description, including higher-privileged users, allowing session token theft and authenticated requests as the victim. The flag is removed on the development branch but remains present in the shipped 15.x and 16.x release lines, so no released version carries the fix.
