## What is CVE-2023-48199?

CVE-2023-48199 is a high-severity cross-site scripting vulnerability in n/a, published on 15 Nov 2023. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

HTML Injection vulnerability in the 'manageApiKeys' component in Grocy <= 4.0.3 allows attackers to inject arbitrary HTML content without script execution. This occurs when user-supplied data is not appropriately sanitized, enabling the injection of HTML tags through parameter values. The attacker can then manipulate page content in the QR code detail popup, often coupled with social engineering tactics, exploiting both the trust of users and the application's lack of proper input handling.

Weakness: CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component)

Check this codebase for CVE-2023-48199 and fix it if it is affected.

What it is: CVE-2023-48199 is a high-severity cross-site scripting vulnerability in n/a, published on 15 Nov 2023. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-48199 in the wild and no public exploit code.

Affected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
