GHSA-4Q3P-RJ5X-XV7P ImageSharp: EXR ZIP decoder can expose stale allocator data after a short inflate

Summary A crafted ZIP-compressed OpenEXR image can return stale memory from a prior ImageSharp operation as decoded pixels. The ZIP decoder accepts a non-empty inflate result shorter than the EXR block's required size, then the EXR decoder reads the full expected block. This is a process-local,...

CVE-2026-106111 ImageSharp: EXR ZIP decoder can expose stale allocator data after a short inflate

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 fu...

CVE-2026-106111

The ImageSharp 2D graphics library (versions 4.0.0 through 4.1.2 ) is vulnerable to a memory disclosure issue in its EXR ZIP decoder. Specifically, the ExrBaseDecompressor.UndoZipCompression method can accept a ZIP or ZIPS inflate result shorter than the required block size. This causes ExrDecode...
