NVD description
The Affinity by Canva application for macOS before 3.3.1 (October 2026 release) did not safely calculate the size of an image buffer when generating QuickLook thumbnails and previews of Affinity document files, leading to an integer overflow and a heap-based buffer overflow. A threat actor could craft an Affinity document that, when displayed or previewed by a user in Finder, could corrupt heap memory and cause the thumbnail or preview extension to crash.
