# Adobe After Effects: malicious file opens lets attacker run code

Link for people: https://infrastack.ai/live/CVE-2026-113534 (this .md is for agents)

Adobe After Effects has an improper input validation flaw. A victim who opens a malicious file can have arbitrary code run in the context of their user account.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:After Effects affected <= 26.5; <= 25.6.6 fixed 26.5.3, 27.0

## How to check

In After Effects open Help > About After Effects (macOS: After Effects > About) or the Creative Cloud desktop app. Affected: 26.5 and earlier, and 25.6.6 and earlier. Fixed: 26.5.3 or 27.0.

## Fix

Update Adobe After Effects to 27.0 (from the 27.x line) or 26.5.3 (from 26.x), or the newest version; 25.6.6 and earlier has no fixed 25.x build listed in the bulletin, so move to 26.5.3 or 27.0.
