# Adobe Media Encoder: out-of-bounds write lets a malicious file run code

Link for people: https://infrastack.ai/live/CVE-2026-113541 (this .md is for agents)

Adobe Media Encoder has an out-of-bounds write flaw that lets a crafted file write past a memory buffer. An attacker who gets a victim to open that file can run code as the current user.

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

## Affected

- vendor:Adobe Media Encoder affected <= 25.6.6, 26.0 - 26.5.2 fixed 26.5.3, 27.0

## How to check

Open Adobe Media Encoder > Help > About (macOS: Media Encoder > About). Affected: 26.5.2 and earlier, and 25.6.6 and earlier. Fixed: 26.5.3 or 27.0.

## Fix

Update Adobe Media Encoder to 27.0, or to 26.5.3 on the 26.x line (25.6.6 and earlier is affected; move to 26.5.3 or 27.0), via Creative Cloud app / Download Center
