Confidentiality: None
Integrity: None
Availability: High

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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

CVE published 10 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed

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

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

European organizations should implement specific mitigations beyond generic advice: 1) Educate users, especially those in media and creative roles, about the risks of opening files from unknown or untrusted sources and the potential for maliciously crafted files to cause application crashes. 2) Enforce strict file validation and scanning policies using advanced endpoint protection solutions that can detect malformed or suspicious audio/project files before they reach Adobe Audition. 3) Isolate Adobe Audition usage to dedicated workstations or virtual environments to contain potential crashes and prevent broader system impact. 4) Maintain regular backups of ongoing projects to minimize data loss from unexpected application failures. 5) Monitor Adobe’s security advisories closely for patches or updates addressing this vulnerability and prioritize timely deployment once available. 6) Consider application whitelisting or sandboxing techniques to restrict execution of unauthorized or suspicious files. 7) Implement network-level controls to limit the distribution of untrusted files within the organization. These targeted steps will reduce the likelihood and impact of exploitation while maintaining operational continuity.

Description

Audition versions 25.3 and earlier are affected by an Access of Memory Location After End of Buffer vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to cause the application to crash or become unresponsive. 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-2026-21316 is operational disruption due to application crashes or unresponsiveness in Adobe Audition. This can affect media production companies, broadcasters, and creative agencies relying on Adobe Audition for audio editing and production workflows. Denial-of-service conditions may delay project timelines and reduce productivity. Although the vulnerability does not compromise data confidentiality or integrity, repeated crashes could lead to loss of unsaved work or require system restarts, impacting availability. The requirement for user interaction limits large-scale automated exploitation but does not eliminate targeted attacks, especially through spear-phishing or malicious file sharing. Organizations with remote or hybrid workforces may face increased risk if users open untrusted files outside secure environments. The absence of known exploits reduces immediate risk but does not preclude future weaponization. Overall, the impact is moderate but significant for sectors dependent on uninterrupted audio processing capabilities.
