LibreOffice advises don’t use OpenOffice!
The developers of LibreOffice, the most popular free and open source alternative to Microsoft’s ubiquitous office suite, are advising against the use of its OpenOffice progenitor due to security vulnerabilities and its lack of development, German news site heise reports.
In a post on Mastodon, they point to security vulnerabilities that have been known for years but still remain unfixed. According to minutes of the Apache board meeting in March 2025, there are three security vulnerabilities in OpenOffice that are more than a year old. This has been confirmed by a representative of the Apache Software Foundation (ASF) security team.

According to the record there are numerous other, previously unaddressed issues with OpenOffice software, including vulnerabilities have existed since at least November 2023. “We are making progress in identifying improvements to address these issues,” the ASF security team representative explains.
LibreOffice: Apache Foundation is harming open source
Furthermore, the LibreOffice developers accuse the ASF of not developing OpenOffice actively any more, but of feigning to do so with minor changes to HTML tags and blank lines. This harms the entire open source community. The ASF has not commented on these allegations. However, OpenOffice has an active project management committee and retains its status as a top-level project within the ASF, according to spokesperson Brian Proffitt. In fact, the recent commits in the OpenOffice GitHub repository have primarily consisted of correcting typographical errors and making minor amendments to translations.
The current version of OpenOffice, 4.1.15, was released in December 2023. It included several bug fixes and dictionary updates, whilst it last received new features with the release of version 4.1 in April 2014. In the light of this, the LibreOffice team recommends using alternatives and in particular its own office suite.
