# Adobe After Effects: out-of-bounds write lets a malicious file run code

Link for people: https://infrastack.ai/live/CVE-2026-113523 (this .md is for agents)

Adobe After Effects has an out-of-bounds write flaw that lets an attacker run code as the current user. Exploitation requires the victim to open a malicious file.

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

## Affected

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

## How to check

## Fix

Update After Effects to 27.0, or to 26.5.3 if staying on the 26.x line (Creative Cloud desktop app or Download Center). Adobe lists no 25.x fixed build: 25.6.6 and earlier are affected, so move to 26.5.3 or 27.0.
