CVE-2021-21102Network attack vector

Code execution via crafted-file path traversal

Published Jun 28, 2021 · Updated Apr 23, 2025

Path traversal in Adobe Illustrator 25.2 and earlier allows remote attackers to execute code as the current user through a crafted file. The Windows document parser fails to constrain attacker-controlled paths while parsing a crafted DOCX file, allowing content to escape its intended directory. Execution requires a victim to open the file, and resulting code runs with the victim's privileges.
