CVE-2026-113516 · Severity: high · CVSS 7.8 · Published 2026-11-10

Adobe After Effects, a professional video compositing and effects software, is vulnerable to multiple out-of-bounds write flaws that could allow attackers to execute arbitrary code on a user's system. An attacker must trick a victim into opening a malicious project or media file, after which the vulnerability is automatically triggered. If exploited, attackers gain full control of the affected system with the privileges of the logged-in user.

## How to fix

- Fixed in After Effects 27.0, After Effects 26.5.3

## Technical details

Multiple out-of-bounds write vulnerabilities (CWE-787), along with stack-based and heap-based buffer overflows, exist in After Effects' file parsing logic. Exploitation requires local file interaction (user opens malicious file) but no special privileges; the vulnerabilities affect multiple parsing code paths. A successful exploit results in arbitrary code execution in the context of the current user.

## Affected products

- Adobe After Effects 26.5 and earlier
