CVE-2026-21314 is a security vulnerability classified as an out-of-bounds read (CWE-125) affecting Adobe Audition versions 25.3 and earlier. This vulnerability arises when the software reads memory outside the bounds of a buffer, potentially exposing sensitive information stored in adjacent memory locations. The flaw can be triggered when a user opens a specially crafted malicious audio file, which causes the application to perform an out-of-bounds read operation. The vulnerability does not allow modification of data or denial of service but can lead to unauthorized disclosure of confidential information held in memory, such as cryptographic keys, user credentials, or other sensitive data. The CVSS 3.1 score of 5.5 reflects a medium severity level, with the attack vector being local (requiring user interaction), low attack complexity, no privileges required, and a high impact on confidentiality. No patches are currently linked, indicating that Adobe may not have released a fix yet or it is pending. No known exploits have been observed in the wild, but the vulnerability poses a risk especially in environments where Adobe Audition is used to process untrusted files. The vulnerability's exploitation requires the victim to open a malicious file, which limits the attack surface but does not eliminate risk, especially in targeted phishing or supply chain attacks.

For European organizations, the primary impact of CVE-2026-21314 is the potential leakage of sensitive information from memory, which could include personal data, intellectual property, or authentication tokens. This could lead to further compromise if attackers use the disclosed information to escalate privileges or move laterally within networks. Organizations in media, broadcasting, and content creation sectors that rely on Adobe Audition are particularly vulnerable. The requirement for user interaction reduces the likelihood of widespread automated exploitation but increases risk in targeted spear-phishing campaigns. Confidentiality breaches could result in regulatory penalties under GDPR if personal data is exposed. The vulnerability does not affect system integrity or availability, so direct disruption is unlikely. However, the exposure of sensitive data could undermine trust and cause reputational damage. Since no patches are currently available, organizations must rely on interim mitigations to reduce risk until a fix is released.

1. Monitor Adobe’s official channels for patch releases and apply updates promptly once available. 2. Restrict the opening of audio files from untrusted or unknown sources within Adobe Audition to minimize exposure to malicious files. 3. Employ endpoint protection solutions that can detect and block malicious file behaviors or suspicious memory access patterns. 4. Educate users about the risks of opening unsolicited or unexpected files, especially in email attachments or downloads. 5. Use application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 6. Implement network segmentation to isolate systems running Adobe Audition from critical infrastructure. 7. Conduct regular memory and process monitoring to detect unusual activity indicative of exploitation attempts. 8. Consider disabling Adobe Audition on systems where it is not essential to reduce the attack surface. 9. Review and enforce strict file validation policies and use file integrity monitoring to detect tampering.
