https://pillow.readthedocs.io/en/stable/releasenotes/12.1.1.html announces
the release of Pillow 12.1.1 on 2026-02-11 with these changes:
Security
--------
CVE-2026-25990: Fix OOB write with invalid tile extents
Check that tile extents do not use negative x or y offsets when decoding or
encoding, and raise an error if they do, rather than allowing an OOB write.
An out-of-bounds write may be triggered when opening a specially crafted
PSD image. This only affects Pillow >= 10.3.0. Reported by Yarden Porat.
Other changes
-------------
Patch libavif for svt-av1 4.0 compatibility
A patch has been added to depends/install_libavif.sh, to allow libavif 1.3.0
to be compatible with the recently released svt-av1 4.0.0.
[At the time of this writing the cached copy on readthedocs has the wrong
CVE id, but https://github.com/python-pillow/Pillow/pull/9430/changes
corrects it in the source document.]
https://github.com/python-pillow/Pillow/security/advisories/GHSA-cfh3-3jmp-rvhc
adds that a workaround is available:
Image.open() has a formats parameter that can be used to prevent PSD images
from being opened.
https://github.com/python-pillow/Pillow/pull/9427 has the source changes for
the fix.
