Description (CNA)
The Affinity by Canva application before 3.3.1 (October 2026 release) did not correctly handle incomplete UTF-8 character sequences when parsing text in Affinity document files, leading to a heap buffer over-read. A threat actor could craft an Affinity document that, when opened by a user in Affinity, could disclose the contents of adjacent heap memory in the document's text or result in an application crash.
