It's extremely risky to keep using OpenOffice. Apache has marked its security status as "Amber" with "three issues in OpenOffice over 365 days old and a number of other open issues not fully triaged."
It's also worrying that The Apache Foundation continues to promote and distribute OpenOffice despite unfixed security issues and zero updates to the software. So many people in the FOSS world have called on them to finally retire it, put it in the Attic and keep up a good reputation for FOSS - but they won't do it. It still gets hundreds of thousands of downloads despite being unfixed.
It's irresponsible of The ASF IMO.
BTW, anyone concerned can email apache at apache dot org and ask why they're still distributing OpenOffice despite vulnerabilities. A few people on Mastodon have done that but gotten no answers yet. The more pressure there is to put it in the Attic, the sooner this awful situation will end...
