CVE-2026-21317
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 that allows memory exposure when processing specially crafted files. An attacker can exploit this by tricking a user into opening a malicious audio file, potentially disclosing sensitive data from the application's memory space.

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.
-
Determine Adobe Audition installed versionOpen Adobe Audition and go to Help > About Adobe Audition, or check the version in Windows Programs and FeaturesAffected if version displayed is 25.3 or earlier (versions below 25.6 are affected)
-
Confirm version number formatNote the full version number (for example, 25.0, 25.3, 24.6) - the first number indicates the major releaseAffected if the version starts with 25.x where x is 3 or lower, or any version below 25.6 such as 24.x series
-
Identify if the application processes audio filesVerify that Adobe Audition is configured to open audio file types (WAV, MP3, FLAC, etc.) - check File > Open or File > Import to see supported formatsAffected if the software can open audio files and the user has permission to open them
-
Assess user file handling behaviorReview whether the system user opens audio files from untrusted or unknown sourcesAffected if users routinely open audio files from email attachments, downloads, or other untrusted sources without validation
You are affected if Adobe Audition version 25.3 or earlier (below 25.6) is installed AND the application is used to open audio files from any source, since the vulnerability triggers during file processing.
Generated from the published advisory. Verify against your own configuration.
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 when a patch is released, and exercise caution when opening audio files from untrusted sources.
Adobe Audition 25.6
- Close Adobe Audition if it is currently running
- Open Adobe Creative Cloud desktop application or navigate to adobe.com/creativecloud
- Search for Adobe Audition in your installed apps
- Update Adobe Audition to version 25.6 or later
- After update completes, verify the installed version by opening Audition and checking Help > About Adobe Audition
- Ensure the version shows 25.6 or higher before opening any untrusted audio files
