Description

The Affinity by Canva application before 3.3.1 (October 2026 release) did not perform adequate bounds checking when parsing raster image data in Affinity document files, leading to an out-of-bounds read and the dereference of an untrusted pointer. A threat actor could craft an Affinity document that, when opened by a user in Affinity, could result in memory corruption or an application crash.
