CVE-2026-106111: ImageSharp is a 2D graphics library

This week

MEDIUM 5.9REMOTEUPGRADE

CVE-2026-106111 is a medium-severity flaw (CVSS 5.9) affecting imagesharp. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

ImageSharp is a 2D graphics library. From 4.0.0 until 4.1.2, ExrBaseDecompressor.UndoZipCompression accepts a nonempty ZIP or ZIPS inflate result that is shorter than the EXR block's required size. ZipExrCompression.Decompress reconstructs the returned prefix while ExrDecoderCore processes the full expected block from a buffer obtained through Configuration.Default, allowing bytes retained from a completed prior ImageSharp operation to appear in

sixlabors imagesharp UPGRADE

Affected: >= 4.0.0 and < 4.1.2

Fixed in: 4.1.2

Safe to downgrade to: a release before 4.0.0

1. Check installed version

apt-cache policy imagesharp || rpm -q imagesharp || imagesharp --version

2. UPGRADE to 4.1.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade imagesharp

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade imagesharp

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 4.0.0 (Debian / Ubuntu)

apt-cache madison imagesharp sudo apt install imagesharp=<VERSION_BEFORE_4.0.0> sudo apt-mark hold imagesharp

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list imagesharp sudo dnf downgrade imagesharp-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add imagesharp

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
