CVE-2026-59205 · Pillow: Controlled heap out-of-bounds write in `ImageCmsTransform.apply()` via output mode mismatch

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Pillow is a Python imaging library. Prior to 12.3.0, Pillow's ImageCms.ImageCmsTransform.apply(im, imOut) API can trigger controlled native heap corruption when the caller supplies an output image whose mode does not match the transform's declared output mode. This issue is fixed in version 12.3.0.
