## What is CVE-2025-64407?

CVE-2025-64407 is a medium-severity missing authorization vulnerability in Apache Openoffice, published on 12 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Apache OpenOffice documents can contain links. A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links 
to be loaded without prompt. Such links could also be used to transmit system information, such as environment variables or configuration settings.

In the affected versions of Apache OpenOffice, documents that used a certain URI scheme linking to external files would 
load the contents of such files without prompting the user for 
permission to do so. Such URI scheme allows to include system configuration data, that is not supposed to be transmitted externally.

This issue affects Apache OpenOffice: through 4.1.15.

Users are recommended to upgrade to version 4.1.16, which fixes the issue.

The LibreOffice suite reported this issue as CVE-2024-12426.

Weakness: CWE-862 (Missing Authorization), CWE-201 (Insertion of Sensitive Information Into Sent Data)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-64407 and fix it if it is affected.

What it is: CVE-2025-64407 is a medium-severity missing authorization vulnerability in Apache Openoffice, published on 12 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-64407 in the wild and no public exploit code.

Affected product: Apache Openoffice. 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.
