CVE-2026-21315 is an out-of-bounds read vulnerability classified under CWE-125 affecting Adobe Audition versions 25.3 and earlier. This vulnerability arises when the software improperly handles memory boundaries while processing certain file inputs, allowing an attacker to read memory locations outside the intended buffer. The flaw can be triggered when a user opens a specially crafted malicious audio file, leading to exposure of sensitive information stored in memory, such as credentials or cryptographic keys. The vulnerability does not allow modification of data or denial of service but compromises confidentiality. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) indicates that the attack requires local access (local vector), low attack complexity, no privileges, and user interaction, with a high impact on confidentiality but no impact on integrity or availability. No patches or exploits are currently publicly available, but the vulnerability is published and should be addressed promptly. Adobe Audition is widely used in professional audio editing, making this vulnerability relevant to media production environments.

For European organizations, the primary impact is the potential exposure of sensitive data held in memory during audio file processing. This could include proprietary audio content, user credentials, or other confidential information, leading to privacy breaches or intellectual property theft. Organizations in media, broadcasting, and creative industries that rely on Adobe Audition are particularly at risk. Although the vulnerability does not allow code execution or system compromise, the confidentiality loss could facilitate further attacks or espionage. The requirement for user interaction limits large-scale automated exploitation but targeted spear-phishing or supply chain attacks remain plausible. The absence of known exploits reduces immediate risk but does not eliminate future threat potential. Compliance with data protection regulations such as GDPR may be impacted if sensitive personal data is exposed.

1. Monitor Adobe’s official channels for patches and apply updates immediately once available to remediate the vulnerability. 2. Until patches are released, restrict the opening of audio files from untrusted or unknown sources within Adobe Audition. 3. Implement endpoint security solutions capable of detecting and blocking malicious file payloads targeting Adobe products. 4. Educate users on the risks of opening unsolicited or suspicious audio files to reduce the likelihood of successful exploitation. 5. Employ application whitelisting and sandboxing techniques to limit the impact of malicious files. 6. Conduct regular audits of systems running Adobe Audition to detect anomalous behavior or memory access patterns. 7. Consider network segmentation to isolate systems used for audio editing from critical infrastructure to contain potential breaches.
