## What is CVE-2024-0435?

CVE-2024-0435 is a high-severity cross-site scripting vulnerability in Mintplexlabs Anythingllm, published on 25 Feb 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

User can send a chat that contains an XSS opportunity that will then run when the chat is sent and on subsequent page loads.

Given the minimum requirement for a user to send a chat is to be given access to a workspace via an admin the risk is low. Additionally, the location in which the XSS renders is only limited to the user who submits the XSS. 

Ultimately, this attack is limited to the user attacking themselves. There is no anonymous chat submission unless the user does not take the minimum steps required to protect their instance.

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

Check this codebase for CVE-2024-0435 and fix it if it is affected.

What it is: CVE-2024-0435 is a high-severity cross-site scripting vulnerability in Mintplexlabs Anythingllm, published on 25 Feb 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-0435 exists.

Affected product: Mintplexlabs Anythingllm. 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.
