Vulnerability description

DayBreach CVE AI Research

CVE-2026-96396 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

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.
