https://seclists.org/oss-sec/2026/q4/497: CVE-2026-59264: Apache OpenOffice: Uncontrolled search path element vulnerability in Windows installer

Q: Who is exposed to this issue?

Systems using the Windows installer for Apache OpenOffice 4.1.16 or earlier are affected. The issue concerns installer execution on Windows, not a stated vulnerability in the installed application itself.

Q: What does an attacker need to exploit it?

The system must already be manipulated before the installer is run. Under that condition, the installer may run external code with elevated access.

Q: What should organizations do?

Upgrade Apache OpenOffice to version 4.1.17, which fixes the issue. Until the upgrade is completed, avoid running affected Windows installers on systems that may have been manipulated.
