Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在3.3.1版本之前（2026年10月发布）的Canva Affinity应用程序，在解析Affinity文档文件中的文本时，未能正确处理不完整的UTF-8字符序列，从而导致堆缓冲区越界读取。攻击者可构造一个恶意的Affinity文档，当用户在Affinity中打开该文档时，可能会泄露文档文本相邻堆内存中的数据，或导致应用程序崩溃。

Vulnerability Description
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.
