CVE-2026-21313: 
Adobe Audition vulnerability analysis and mitigation

CVE-2026-21313 is an out-of-bounds read vulnerability in Adobe Audition that can lead to sensitive memory disclosure. It affects Adobe Audition versions 25.3 and earlier (all versions prior to 25.6). Adobe disclosed and patched this vulnerability on February 10, 2026, as part of its February 2026 security update cycle. It carries a CVSS v3.1 base score of 5.5 (Medium) (Adobe Advisory).

The vulnerability is classified as CWE-125 (Out-of-bounds Read), occurring when Adobe Audition processes a specially crafted malicious file without properly validating memory boundaries during read operations. The attack vector is local, requiring no special privileges, but does require user interaction — specifically, a victim must open a malicious file in Audition. This maps to CAPEC-540 (Overread Buffers), where an attacker supplies a crafted input file that causes the application to read beyond the intended memory buffer, potentially exposing adjacent memory contents (Adobe Advisory).

Successful exploitation results in a high confidentiality impact, with no effect on integrity or availability. An attacker who tricks a victim into opening a malicious audio or project file in Adobe Audition could read sensitive data from the application's memory, potentially exposing credentials, cryptographic keys, or other in-memory confidential information. The scope is limited to the local system and the Audition process context, with no direct path to lateral movement or code execution based on this vulnerability alone (Adobe Advisory).

Adobe has released a patch addressing this vulnerability in Adobe Audition version 25.6. Users running Audition 25.3 or any earlier version should update to version 25.6 or later immediately via the Creative Cloud desktop application or Adobe's official download channels. As an additional precaution, users should be educated to avoid opening untrusted or suspicious audio/project files, and organizations may consider implementing file type restrictions or application whitelisting where feasible (Adobe Advisory).

The vulnerability was noted by CIS (Center for Internet Security) in its advisory covering multiple Adobe product vulnerabilities from the February 2026 patch cycle, and was tracked by Tenable in its plugin pipeline. No significant independent researcher commentary or notable social media discussion has been identified for this specific CVE, consistent with its medium severity and lack of active exploitation (CIS Advisory).
