Code execution via crafted-file out-of-bounds write
Published Sep 2, 2021 · Updated Apr 23, 2025
Out-of-bounds write in Adobe After Effects 18.2.1 and earlier allows attackers to execute code through a crafted file. Its file parser writes beyond an allocated buffer while processing attacker-controlled file data; Adobe has not identified the specific parser or field. Exploitation requires a victim to open the malicious file, after which code runs with the victim's current-user privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=unspecified <=18.2.1
- Affected versionversion=unspecified <=None
