Technical Overview of CVE-2026-47968
CVE-2026-47968 is a critical vulnerability affecting Adobe Audition, a professional audio editing and restoration software. The flaw resides in how the application handles malformed or crafted input files during parsing. Specifically, it is an out-of-bounds write vulnerability, categorized under CWE-787. This occurs when the software writes data beyond the allocated memory buffer boundaries, which can corrupt adjacent memory regions.
The vulnerability is triggered when a user opens a specially crafted malicious file in Adobe Audition. Due to insufficient validation of input data, the application may write data to a memory location outside the intended buffer. This out-of-bounds write can overwrite critical program data, including function pointers or return addresses, thereby allowing an attacker to hijack the execution flow.
The CVSS v3.1 vector string for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. This translates to a Base Score of 7.8 (HIGH). The attack vector is local (AV:L), meaning the exploit requires the attacker to have local access or trick the user into interacting with malicious content. The attack complexity is low (AC:L), indicating that the exploit is relatively straightforward to execute once the malicious file is opened. No privileges are required (PR:N) to exploit this vulnerability, but user interaction is necessary (UI:R) as the victim must open the malicious file. The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), meaning successful exploitation can lead to full compromise of the affected system.
The vulnerability affects Adobe Audition versions up to 25.6.4 and 26.0, with patched versions being 25.6.6 and 26.3 respectively. The vendor, Adobe, has released security updates to address this issue, as part of their monthly security update (APSB26-71). Given the high severity and the requirement for user interaction, this vulnerability poses a significant risk, especially in environments where users regularly open audio files from untrusted sources.
DailyCVE Form:
Platform: Adobe Audition
Version: ≤25.6.4 & 26.0
Vulnerability: Out-of-bounds Write
Severity: HIGH (CVSS 7.8)
date: 2026-07-14
Prediction: 2026-07-14 (Patch Available)
What Undercode Say:
Analytics:
- Exploitability: High – requires only user interaction (opening a file).
- Prerequisites: Victim must open a malicious
.sesx,.aup, or other project/audio files supported by Audition. - Attack Vector: Local (malicious file delivered via email, web download, or removable media).
- Confidence: Confirmed – vendor advisory and NVD entry published.
- Temporal Score: 7.8 (HIGH) – no known public exploits at time of analysis, but proof-of-concept likely to emerge.
Bash Commands & Codes
Check Installed Version (Windows):
wmic product where "name like 'Adobe Audition%%'" get name,version
Check Installed Version (macOS):
ls /Applications/ | grep "Adobe Audition" defaults read /Applications/Adobe\ Audition\ /Contents/Info.plist CFBundleShortVersionString
Manual Update via Adobe Creative Cloud:
On macOS, update using Creative Cloud CLI (if installed) /Applications/Utilities/Adobe\ Creative\ Cloud/CCXProcess/CCXProcess.app/Contents/MacOS/CCXProcess --update
Fingerprinting Vulnerable Systems (Nmap Script Example):
nmap -p 443 --script http-adobe-audition-version <target_ip>
Exploit Simulation (Proof-of-Concept Snippet – Python):
Craft a malformed .sesx file to trigger out-of-bounds write
This is a conceptual example; actual exploit requires reverse engineering.
with open("malicious.sesx", "wb") as f:
f.write(b"\x00" 0x1000) oversized chunk
f.write(b"\x41" 0x200) overflow data
Exploit:
An attacker can craft a malicious audio project file (e.g., `.sesx` or .aup) that contains a specially crafted header or chunk data. When Adobe Audition parses this file, it fails to properly validate the size of an incoming data block, leading to an out-of-bounds write. This can overwrite a function pointer on the stack or heap, allowing the attacker to redirect execution to shellcode embedded within the file. The exploit achieves arbitrary code execution with the privileges of the current user. Since no privileges are required and user interaction is minimal (opening the file), this vulnerability is highly attractive for phishing campaigns and targeted attacks.
Protection:
- Apply Vendor Patch: Update Adobe Audition to version 25.6.6 or 26.3 or later, as provided in Adobe Security Bulletin APSB26-71.
- User Awareness: Educate users to avoid opening audio or project files from untrusted or unknown sources.
- File Restriction: Implement email and web gateway filters to block incoming
.sesx,.aup, and other Audition project file types unless from trusted senders. - Endpoint Detection: Deploy EDR solutions that monitor for abnormal process behavior, such as unusual memory writes or child process creation from Audition.
- Principle of Least Privilege: Run Adobe Audition with the lowest possible user privileges to limit the impact of successful exploitation.
Impact:
- Confidentiality: An attacker can read sensitive information from the victim’s system, including documents, credentials, and other private data.
- Integrity: The attacker can modify or delete files, install malware, or alter system configurations.
- Availability: The attacker can crash the application or cause system instability, potentially leading to denial of service.
- Overall: Successful exploitation grants the attacker the ability to execute arbitrary code with the same privileges as the current user, leading to full system compromise in many scenarios. This poses a severe risk to individuals and organizations that rely on Adobe Audition for audio production and editing.
