CVE-2022-27784

Code execution via crafted-file stack overflow

Published May 6, 2022 · Updated Apr 23, 2025

Stack-based buffer overflow in Adobe After Effects 22.2.1 and earlier and 18.4.5 and earlier allows attackers to execute code via a crafted file. After Effects insecurely handles attacker-controlled file data and overflows a stack buffer while parsing it; Adobe has not disclosed the affected parser or operation. Exploitation requires the current user to open the file, after which code runs with that user's privileges.
