CVE-2026-113523 · Severity: high · CVSS 7.8 · Published 2026-11-10

Adobe After Effects, a professional video editing and motion graphics application, is affected by multiple out-of-bounds write vulnerabilities that could allow an attacker to execute arbitrary code on a user's system. An attacker would need to trick a user into opening a specially crafted malicious file, giving the attacker the ability to run code with the privileges of the user running After Effects.

## How to fix

- Fixed in After Effects 27.0, After Effects 26.5.3

## Technical details

Multiple out-of-bounds write (CWE-787) vulnerabilities exist in After Effects' file parsing logic, along with buffer overflows and path traversal issues. Exploitation requires user interaction—opening a malicious file locally—and results in arbitrary code execution within the current user's security context. Adobe has not reported active exploits in the wild for these issues.

## Affected products

- Adobe After Effects 26.5 and earlier
