CVE-2026-113545 · Severity: high · CVSS 7.8 · Published 2026-11-10

Adobe Media Encoder, a video encoding and publishing platform, is affected by multiple out-of-bounds write vulnerabilities that could allow arbitrary code execution when a user opens a malicious media file. An attacker can exploit this to execute code with the privileges of the logged-in user, potentially compromising the system. This vulnerability requires user interaction but poses a serious risk to media production workflows.

## Technical details

Multiple out-of-bounds write vulnerabilities (CWE-787) in Adobe Media Encoder allow arbitrary code execution in the context of the current user. The vulnerabilities are triggered by local attack vector with user interaction required (opening a malicious file), and do not require elevated privileges or special configuration. A successful exploit gains arbitrary code execution within the user's security context.

## Affected products

- Adobe Media Encoder 26.5.2 and earlier, 25.6.6 and earlier
