## What is CVE-2024-10821?

CVE-2024-10821 is a high-severity denial of service vulnerability in invoke-ai/invokeai, published on 20 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A Denial of Service (DoS) vulnerability in the multipart request boundary processing mechanism of the Invoke-AI server (version v5.0.1) allows unauthenticated attackers to cause excessive resource consumption. The server fails to handle excessive characters appended to the end of multipart boundaries, leading to an infinite loop and a complete denial of service for all users. The affected endpoint is `/api/v1/images/upload`.

Weakness: CWE-835 (Loop with Unreachable Exit Condition)

Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-10821 exists.

Affected packages and fixed versions:
- invokeai (PyPI): affected all versions up to 5.0.2; no fix listed
- invokeai (PyPI): affected all versions up to 5.0.2; no fix listed
- InvokeAI (PyPI): affected all versions up to 5.0.2; no fix listed

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.
