GHSA-GWG2-R3HJ-4W44 ImageSharp: ICC CLUT parsing allocates from unvalidated channel and grid dimensions

Summary A malformed embedded ICC profile can make ImageSharp allocate memory from attacker-controlled CLUT channel and grid dimensions before verifying that the declared CLUT values are present. In published v1 through v3 packages, the public lazy ICC parser allocates approximately 115 MB from th...

CVE-2026-106114

ImageSharp is a 2D graphics library. From 1.0.0-beta0001 until 4.1.2, ICC CLUT parsing calculates allocation sizes from attacker-declared channel and grid dimensions before confirming that the profile contains the declared values. IccDataReader.ReadClutF32 can request a large float array, and...

CVE-2026-106114

The ImageSharp 2D graphics library (versions 1.0.0-beta0001 through 4.1.2 ) is vulnerable to a memory allocation issue during ICC CLUT parsing . The root cause is that the library calculates allocation sizes using attacker-declared channel and grid dimensions without first verifying if the profil...
