Should you update to LibreOffice 26.2.6?
Yes, soon. LibreOffice 26.2.6 is a security update The Document Foundation released on 5 Nov 2026 for Mac, Windows and Linux. It fixes 1 security flaw.[1] None of them is known to be used in attacks.
It is the newest LibreOffice 26.2 release, so it’s the one to have.
Should you update?
Yes, soon. None of its fixes is known to be used in attacks yet. Automatic updates will install it for you. Every security update closes holes that become public the moment it ships, so the risk of staying on the old version only grows. Waiting a week to see if others hit problems is a common habit; with a security update it’s the wrong trade.
Is LibreOffice 26.2.6 safe to install?
Yes. It’s The Document Foundation’s own security release, and updates rarely go wrong; a backup makes it painless if one does. The one unsafe way to get it is from a link: The Document Foundation never sends updates by email, text or pop-up, so install it only from libreoffice.org/download.
What it fixes
The Document Foundation lists 1 security flaw.[1] The Document Foundation doesn’t rate them by severity. They are:
| Flaw | Severity | What The Document Foundation calls it |
