Attack Vector: Local
Attack Complexity: Low
Privileges Required: None
User Interaction: Required
Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

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.

Description

Audition 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.

Impact

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.

Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
