CVE-2021-36047

User-assisted code execution as current user

Published Sep 1, 2021 · Updated Nov 3, 2025

Improper input validation in Adobe XMP Toolkit SDK 2020.1 and earlier allows attackers to execute code via a crafted file. Adobe identifies the flaw class but has not published the affected parser, function, input field, or incorrect validation operation. A victim must open the file, and resulting code runs with the victim's current-user privileges, permitting control of that user's process context.
