CVE-2026-21317 · Severity: medium · CVSS 5.5 · Published 2026-02-10

Adobe Audition, a professional audio editing application, contains a memory reading vulnerability that occurs when processing malicious audio files. An attacker could craft a specially designed file that, when opened by a user, exposes sensitive data from the application's memory to the attacker. This could compromise confidential information such as passwords, encryption keys, or other sensitive data processed by the application.

## Technical details

The vulnerability is an out-of-bounds read flaw in Audition's file parsing logic affecting versions 25.3 and earlier. When processing a malicious file, the application reads memory beyond intended boundaries, potentially exposing sensitive information. The attack requires user interaction—a victim must open a specially crafted file—making it a local, user-driven exploitation vector. An attacker can leverage this to disclose sensitive data stored in process memory. Adobe has addressed this issue in later versions.
