HIGH 7.5REMOTEUPGRADE

CVE-2026-106112 is a high-severity flaw (CVSS 7.5) 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, ICC LUT16 conversion accepts more than four output channels even though ClutCalculator.Calculate and LutEntryCalculator.CalculateLut store intermediate and output values in Vector4. When DecoderOptions.ColorProfileHandling is set to Convert, a malformed embedded profile can direct interpolation and output-LUT operations to write one float per declared channel beyond the four-float desti

Timeline

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)

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.
