CVE-2026-21315: 
Adobe Audition vulnerability analysis and mitigation

CVE-2026-21315 is an Out-of-bounds Read vulnerability in Adobe Audition that can lead to 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 their February 2026 security update cycle. It carries a CVSS v3.1 base score of 5.5 (Medium) (Adobe Advisory, Feedly).

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 low attack complexity and no privileges, but does require user interaction — specifically, a victim must open a malicious audio or project file. When triggered, the out-of-bounds read exposes contents of process memory beyond the intended buffer, potentially leaking sensitive data. This vulnerability maps to CAPEC-540 (Overread Buffers) (Adobe Advisory, Feedly).

Successful exploitation results in a high confidentiality impact with no effect on integrity or availability. An attacker who convinces a victim to open a malicious file could read sensitive information from the Audition process memory, potentially exposing passwords, authentication tokens, or other confidential data loaded in memory at the time of exploitation. The scope is limited to the affected process and does not provide code execution capability on its own (Adobe Advisory, Feedly).

1. Craft a malicious file: Create a specially crafted audio or project file (e.g., a malformed WAV, AIF, or Audition project file) designed to trigger an out-of-bounds read when parsed by Adobe Audition versions 25.3 or earlier.
2. Deliver the file: Distribute the malicious file to a target via phishing email, malicious download link, shared network drive, or other social engineering method.
3. Induce user interaction: Convince the victim to open the malicious file in Adobe Audition, triggering the vulnerable file parsing code path.
4. Trigger out-of-bounds read: The application reads beyond the intended memory buffer during file processing, exposing adjacent process memory contents.
5. Extract sensitive data: Depending on the exploit implementation, the attacker may be able to capture leaked memory contents (e.g., via a crafted file that encodes memory data into output or error channels), potentially recovering passwords, tokens, or other sensitive data from the Audition process memory (Adobe Advisory, Feedly).

• File System: Unexpected or unsolicited audio/project files (e.g., .wav, .aif, .sesx) received via email or downloaded from untrusted sources and opened in Adobe Audition.
• Process: Adobe Audition process (Adobe Audition.exe) exhibiting unusual memory access patterns or crashing unexpectedly upon opening a specific file, which may indicate a triggered out-of-bounds read.
• Logs: Application crash logs or Windows Error Reporting entries referencing Adobe Audition with access violation or memory read errors at unexpected addresses.
• Network: Outbound network connections from the Audition process to unexpected external hosts shortly after opening an untrusted file (may indicate a chained exploit scenario).

Adobe has released a patch in Adobe Audition version 25.6, which resolves this vulnerability. Users should update Adobe Audition to version 25.6 or later immediately via the Creative Cloud desktop application or Adobe's official download channels. As a precautionary measure, users should avoid opening Audition files received from untrusted or unknown sources. Organizations may also consider implementing application sandboxing or file inspection controls for media files in high-risk environments (Adobe Advisory, CIS Advisory).

The CIS (Center for Internet Security) issued an advisory noting multiple vulnerabilities in Adobe products patched in February 2026, including this issue, flagging the potential for sensitive data exposure (CIS Advisory). Tenable published detection plugins for this vulnerability (Nessus plugin 298517), enabling automated scanning for unpatched Audition installations (Tenable). No significant social media discussion or notable independent researcher commentary has been identified for this specific CVE.
