Collabora Office Classic 25.04.12

Released 31/08/2026

Fixes & Improvements

• Security hardening across import filters and font handling: numerous fixes for memory safety issues found by fuzzing in the EMF/EMF+/WMF, PCT, RTF, PDF and drawing import filters, and in the CFF/Type 1 font conversion code (bounds checking, integer overflow, null dereference, and short-read fixes).
• Firebird/Base database hardening: embedded Firebird databases are now handled more safely — databases are only written back if actually opened, event triggers of attached databases are not executed, files are kept in a single directory, and a regression connecting to external Firebird databases was fixed (tdf#172935).
• Safer handling of document-supplied external data: Calc external data providers are only built when needed, SQL table names are quoted, hosts are checked when fetching external data ranges, exotic URL protocols are no longer loaded for document-supplied data, and the GStreamer media backend is limited to simple self-contained media.
• Bundled library updates: NSS 3.126, libxml2 2.15.3, poppler 26.07.0, libtiff 4.7.2, expat 2.8.2, liblangtag 0.6.8, plus curl patches for CVE-2026-8927 and CVE-2026-11856.
• Writer improvements: correct ordering of inline headings in the table of contents, headings with linked character styles are preserved in the TOC, comment marks stay deleted after highlighting their anchor, hiding of delete-then-format interdependent redlines (cool#15951), and an autocorrect undo fix for typographic quotes.
• Read-only configuration support: options locked by the administrator (finalized configuration items) are now shown as disabled throughout the UI in Writer, Calc, Impress and the dialogs, and writes to them are safely ignored.
• Rendering fixes: automatic font color is now resolved per render target (fixing dark-mode issues, including against an edited shape’s own fill), and the dark-mode document background of charts is no longer printed.

CODE 25.04.4.1

Released 17/07/2025

Features

• Handle links in PDF documents like in other document types.

• New WOPI CheckFileInfo property: UserCanOnlyManageRedlines . If set to “true”, a specific feature-restricted mode is activated, which is similar to read-only mode, but allows the user to see and manage tracked changes: accept / reject / comment on them. This implies “UserCanWrite”.

Original source

Landlock-based jails

The secure Kit jails can now be built on the Linux Landlock LSM as an alternative to the capability/chroot-based setup, allowing deployment without extra privileges; the Landlock jails also forbid creating named pipes and sockets.

PDF export fixes

R6 encryption is used for PDF 1.7, encryption works with an empty user password, PDF 2.0 incremental stream encryption was fixed, hidden Calc sheets are no longer exported, and comments are no longer included in printed PDFs.

Copy as Markdown

Writer gained a copy-as-markdown option; a Markdown import encoding bug (wrongly using the system encoding) was also fixed.

Dark mode improvements

Cell cursor, drawing and background colors in Writer, Calc and Impress are now resolved per view, charts follow the dark document background, and automatic font color is resolved against the edited shape’s own fill.

Calc improvements

Hyperlinks can be applied to only the selected text within a cell, per-view filter and hidden-column state survives content syncs and column inserts/deletes, whole-column insert/delete works on a filtered sheet view, pasted shapes land at the cell where paste was issued, and the CSV export/import dialogs were made asynchronous.

Better save feedback

DOCX export now reports progress in the browser, the save indicator ends correctly when an export fails, and saved state is shown for non-ODF formats.

Mobile UI fixes

The Calc cell cursor scrolls into view while the keyboard is open, the canvas resizes back after the keyboard hides, sheet protection is available from the tab context menu with a proper lock icon, and long-press menu entries no longer show raw HTML.

Interoperability fixes

Improved DOCX layout of tables next to anchored frames and auto-width frames, VML textbox wrapping, list bullets recoded from legacy StarOffice symbol fonts, custom XML values set via XPath in DOCX export, and honoring a zero default tab stop distance from DOCX. Setting a password on binary MS Office documents is no longer offered, as it cannot be done securely.

Stability fixes

Original source

This is a security and stability release. Highlights

• Bundled third-party libraries updated to pick up upstream security fixes, including curl (CVE-2026-5545, CVE-2026-6253, CVE-2026-7168, CVE-2026-1965, CVE-2026-3783, CVE-2026-3784, CVE-2025-9086, CVE-2025-10148), libtiff (CVE-2026-4775), harfbuzz (CVE-2026-22693), and refreshed versions of NSS, OpenSSL, libpng, expat, freetype, lcms2, graphite, libcmis, raptor, dlplibs and PostgreSQL.

• Hardened parsing of malformed documents. Numerous fixes to bounds and length checks across the EMF/EMF+, drawing layer, EXIF, OLE and polygon import paths guard against crashes and out-of-bounds reads when opening crafted files.

• Comment author is now taken from the editing view rather than the command, ensuring comments are attributed to the correct user.

• Server hardening: session cookies are now flagged HttpOnly.
