CVE-2026-81731: Frappe 15.11.0 through 16.32.0 stores and renders the workspace card description without XSS filtering

Routine

MEDIUM 5.4UPGRADE

CVE-2026-81731 is a medium-severity flaw (CVSS 5.4) affecting frappe. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

frappe frappe UPGRADE

Affected: >= 15.11.0 and <= 16.32.0

Fixed in: newer than 16.32.0

Safe to downgrade to: a release before 15.11.0

1. Check installed version

apt-cache policy frappe || rpm -q frappe || frappe --version

2. UPGRADE to newer than 16.32.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade frappe

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade frappe

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 15.11.0 (Debian / Ubuntu)

apt-cache madison frappe sudo apt install frappe=<VERSION_BEFORE_15.11.0> sudo apt-mark hold frappe

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list frappe sudo dnf downgrade frappe-<VERSION_BEFORE_15.11.0> sudo dnf versionlock add frappe

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
