Canva 公司的 Affinity 应用 for macOS 在 3.3.1 版本之前（2026 年 10 月发布）在生成 Affinity 文档文件的 QuickLook 缩略图和预览图时，未进行充分的边界检查，导致出现堆读取越界漏洞。攻击者可构造一个特制的 Affinity 文档，当用户在 Finder 中查看或预览该文档时，可能在渲染的缩略图或预览图中泄露相邻堆内存的内容，包括内存地址等信息。

Vulnerability Description
The Affinity by Canva app for macOS before 3.3.1 (October 2026 release) did not perform adequate bounds checking when generating QuickLook thumbnails and previews of Affinity document files, leading to an out-of-bounds heap read. A threat actor could craft an Affinity document that, when displayed or previewed by a user in Finder, could disclose the contents of adjacent heap memory, including memory addresses, in the rendered thumbnail or preview image.
