## What is CVE-2024-3283?

CVE-2024-3283 is a high-severity vulnerability in Mintplexlabs Anythingllm, published on 10 Apr 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

A vulnerability in mintplex-labs/anything-llm allows users with manager roles to escalate their privileges to admin roles through a mass assignment issue. The '/admin/system-preferences' API endpoint improperly authorizes manager-level users to modify the 'multi_user_mode' system variable, enabling them to access the '/api/system/enable-multi-user' endpoint and create a new admin user. This issue results from the endpoint accepting a full JSON object in the request body without proper validation of modifiable fields, leading to unauthorized modification of system settings and subsequent privilege escalation.

Weakness: CWE-915 (Improperly Controlled Modification of Dynamically-Determined Object Attributes)

What it is: CVE-2024-3283 is a high-severity vulnerability in Mintplexlabs Anythingllm, published on 10 Apr 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-3283 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.
