## What is CVE-2023-41167?

CVE-2023-41167 is a medium-severity cross-site scripting vulnerability in n/a, published on 25 Aug 2023. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official description

@webiny/react-rich-text-renderer before 5.37.2 allows XSS attacks by content managers. This is a react component to render data coming from Webiny Headless CMS and Webiny Form Builder. Webiny is an open-source serverless enterprise CMS. The @webiny/react-rich-text-renderer package depends on the editor.js rich text editor to handle rich text content. The CMS stores rich text content from the editor.js into the database. When the @webiny/react-rich-text-renderer is used to render such content, it uses the dangerouslySetInnerHTML prop, without applying HTML sanitization. The issue arises when an actor, who in this context would specifically be a content manager with access to the CMS, inserts a malicious script as part of the user-defined input. This script is then injected and executed within the user's browser when the main page or admin page loads.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
