Link for people: https://infrastack.ai/live/CVE-2026-113528 (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 needs 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 fixed 26.5.3
- vendor:After Effects 25.x affected <= 25.6.6 fixed 27.0

## How to check

Help > About After Effects (Windows) or After Effects > About After Effects (macOS). Exposed if the version is 26.5 or earlier on the 26.x line (fixed in 26.5.3), or 25.6.6 or earlier on the 25.x line (fixed in 27.0).

## Fix

Update After Effects to 26.5.3 or later (26.x line) or to 27.0 (25.6.x line, per the CVE record). Via Creative Cloud desktop app.
