## What is CVE-2023-29046?

CVE-2023-29046 is a medium-severity denial of service vulnerability in Open-Xchange Open-Xchange Appsuite, published on 2 Nov 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Connections to external data sources, like e-mail autoconfiguration, were not terminated in case they hit a timeout, instead those connections were logged. Some connections use user-controlled endpoints, which could be malicious and attempt to keep the connection open for an extended period of time. As a result users were able to trigger large amount of egress network connections, possibly exhausting network pool resources and lock up legitimate requests. A new mechanism has been introduced to cancel external connections that might access user-controlled endpoints. No publicly available exploits are known.

Weakness: CWE-400 (Uncontrolled Resource Consumption)

Check this codebase for CVE-2023-29046 and fix it if it is affected.

What it is: CVE-2023-29046 is a medium-severity denial of service vulnerability in Open-Xchange Open-Xchange Appsuite, published on 2 Nov 2023. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-29046 in the wild and no public exploit code.

Affected product: Open-Xchange Open-Xchange Appsuite. 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.
