CVE-2026-21313
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAudition versions 25.3 and earlier are affected by an out-of-bounds read vulnerability that could lead to memory exposure. An attacker could leverage this vulnerability to disclose sensitive information stored in memory. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAdobe Audition versions 25.3 and earlier contain an out-of-bounds read vulnerability in file parsing logic. When a user opens a specially crafted malicious file, the application reads memory beyond allocated buffer boundaries, potentially exposing sensitive data stored in process memory to the attacker.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Adobe Audition is installedCheck for the presence of Adobe Audition in typical installation directories: C:\Program Files\Adobe\Adobe Audition XX\Audition.exe on Windows, or /Applications/Adobe Audition XX on macOS. Also check the Windows Start menu or macOS Applications folder for the application icon.Affected if Adobe Audition software is present on the system
-
Determine installed version numberRight-click the Audition.exe file (Windows) or Audition app (macOS), select Properties/Get Info, and view the File Version or Product Version field. Alternatively, launch Adobe Audition and go to Help > About Adobe Audition to display the exact version number.Affected if The displayed version is 25.3 or earlier, or any version number below 25.6
-
Confirm file parsing feature is accessibleThe vulnerability triggers when opening specially crafted audio files. Verify that the application can open and parse files by checking if the File > Open or File > Import functions are available and functional in the installed version.Affected if The file open/import functionality is present and operational in the application
If Adobe Audition is installed and the version is 25.3 or earlier (any version below 25.6), the environment is affected by this out-of-bounds read vulnerability in file parsing logic.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped25.6
Update Adobe Audition to a version newer than 25.3. Until patched, avoid opening files from untrusted sources.
Adobe Audition 25.6
- Upgrade Adobe Audition to version 25.6 or later to resolve the out-of-bounds read vulnerability
