CVE-2026-90632Apache OpenOffice files accessible to external parties
CVE-2026-90632 is a files accessible to external parties in Apache OpenOffice, rated medium (5.5 on CVSS 3.1).
Why this priority: Medium severity, with no exploitation signal.
Published · Updated · NVD status: Modified
What it is
Files or folders that should be private can be fetched from outside.
How it is reached
An attacker can exploit it by someone who can already run code or sign in on the machine, without an account, but someone has to act first, such as opening a file or following a link.
What an attacker gains
A successful attack can read the data it protects. In practice, this kind of flaw lets an attacker learn data or internals that help a follow-up attack.
Is it being exploited?
There is no public report of exploitation yet. EPSS estimates a 0.22% chance of exploitation activity in the next 30 days, higher than 13% of scored CVEs.
What to do
- Upgrade Apache OpenOffice to 4.1.17 or later.
- Limit who can run code or sign in on the hosts that run it.
- Warn the people who use it, and filter files and links on the way in.
Description from NVD
Apache OpenOffice documents can include multimedia content (audio, video, etc.)
A crafted document could exploit the GStreamer multimedia component of Apache OpenOffice version through 4.1.16 to load the contents of any local file, and include them when the document is saved or exported, for example as PDF.
Users are recommended to upgrade to version 4.1.17, which fixes this issue.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Error responses, logs and debug endpoints. The flaw sits between internal data and whoever can read the response or log.
- APIs that over-share. The flaw sits between internal data and whoever can read the response or log.
Trust boundaries in play
- Host boundary. The attacker needs a foothold on the machine first; the flaw turns a small foothold into a bigger one.
- People who open files and links. Mail, chat and browsers are the delivery path.
- Between internal data and whoever can read the response or log. An attacker who crosses it can learn data or internals that help a follow-up attack.
Questions to answer about your own systems
- Where does Apache OpenOffice run in your systems, and at which version?
- Which of those hosts also run code or users you do not fully trust?
- What can it reach once compromised: which data stores, secrets and services?
