Full Report
Multiple vulnerabilities have been discovered in Adobe products, the most severe of which could allow for arbitrary code execution.Adobe Bridge is a creative asset manager that lets you preview, organize, edit, and publish multiple creative assets quickly and easily.Adobe Dreamweaver is a web design integrated development environment (IDE) that is used to develop and design websites.Adobe InDesign is a professional page layout and desktop publishing software used for designing and publishing content for both print and digital media.Adobe InCopy is a professional word processor designed for writers and editors to collaborate with designers on documents simultaneously.Adobe Photoshop is a powerful raster graphics editor developed by Adobe for image creation, editing, and manipulation.Adobe Illustrator is a professional vector graphics editor used for creating logos, icons, typography, and other scalable graphics that retain clarity at any size.Adobe Substance 3D is a suite of tools for creating 3D content, including modeling, texturing, and rendering.Adobe ColdFusion is a rapid development platform for building and deploying web and mobile applications.Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Analysis Summary
This summary consolidates the information regarding multiple vulnerabilities discovered across various Adobe products. Specific CVEs, severity information, and patching details required further review from a formal Adobe security advisory, as the provided text lists only technical details without assigned CVSS scores or specific patch versions, except for the affected software versions.
# Vulnerability: Multiple Critical Vulnerabilities in Adobe Products Leading to Arbitrary Code Execution
## CVE Details
* **CVE ID:** Multiple (Including CVE-2026-21283, CVE-2026-21267 through CVE-2026-21272, CVE-2026-21274, CVE-2026-21281, CVE-2026-21275 through CVE-2026-21278, CVE-2026-21304, CVE-2026-21308, CVE-2026-21298 through CVE-2026-21303, CVE-2026-21287, CVE-2025-66516, CVE-2026-21280, CVE-2026-21288, CVE-2026-21305, CVE-2026-21306)
* **CVSS Score:** Not explicitly stated in the advisory text. (Severity is implied as high due to RCE potential).
* **CWE:** Various memory corruption (Heap Buffer Overflow, Out-of-bounds Read/Write, Use After Free), Input Validation, OS Command Injection, and XML External Entity Injection (for ColdFusion).
## Affected Systems
* **Products:** Adobe Bridge, Adobe Dreamweaver, Adobe InCopy, Adobe InDesign, Adobe Substance 3D Designer, Adobe Substance 3D Modeler, Adobe Substance 3D Painter, Adobe Substance 3D Sampler, Adobe Substance 3D Stager, Adobe Illustrator, Adobe ColdFusion.
* **Versions:**
* Adobe Bridge: 15.1.2 (LTS) and earlier; 16.0 and earlier
* Adobe Dreamweaver: 21.6 and earlier
* Adobe InCopy: 19.5.5 and earlier; 21.0 and earlier
* Adobe InDesign: ID19.5.5 and earlier; ID21.0 and earlier
* Adobe Substance 3D Designer: 15.0.3 and earlier
* Adobe Substance 3D Modeler: 1.22.4 and earlier
* Adobe Substance 3D Painter: 11.0.3 and earlier
* Adobe Substance 3D Sampler: 5.1.0 and earlier
* Adobe Substance 3D Stager: 3.1.5 and earlier
* ColdFusion: 2023 Update 17 and earlier; 2025 Update 5 and earlier
* Illustrator: 2025 29.8.3 and earlier; 2026 30.0 and earlier
* **Configurations:** Affects systems processing specially crafted files or using vulnerable components. The impact is higher for users operating with administrative rights.
## Vulnerability Description
Multiple flaws across various Adobe applications could lead to memory corruption, improper input handling, improper authorization, and path traversal issues. The most severe vulnerabilities (e.g., Heap-based Buffer Overflow in Bridge, OS Command Injection in Dreamweaver) could allow a remote or local attacker to achieve **Arbitrary Code Execution (ACE)** in the security context of the currently logged-on user. Exploitation allows an attacker to install programs, manipulate data, or create new user accounts.
## Exploitation
* **Status:** Not exploited in the wild (as of the advisory date). PoC availability is not mentioned.
* **Complexity:** Varies by vulnerability, but ACE implies medium to high complexity depending on the specific exploit chain required.
* **Attack Vector:** Likely Network (for ColdFusion/Dreamweaver) or Local/Adjacent (for file processing vulnerabilities in other applications).
## Impact
* **Confidentiality:** High (If ACE achieved, information disclosure is possible).
* **Integrity:** High (Ability to view, change, or delete data, and install programs).
* **Availability:** High (System disruption or complete takeover possible upon successful ACE).
## Remediation
### Patches
* *Note: Specific patch versions were not provided in this summary context. Users must consult the official Adobe Security Bulletins associated with MS-ISAC ADVISORY NUMBER: 2026-005.*
### Workarounds
* No specific workarounds were detailed in the provided summary text. Mitigation generally involves restricting user privileges where possible, especially for lower-privileged accounts.
## Detection
* **Indicators of Compromise:** IOCs would depend on the specific exploit leveraged (e.g., unusual process spawning from Adobe application executables, unexpected network activity, file modifications in the user profile directories).
* **Detection Methods and Tools:** Standard endpoint detection and response (EDR) solutions monitoring for unexpected child processes spawned by Adobe applications (Bridge, Photoshop, ColdFusion runtime, etc.) should be utilized. Monitoring for attempts to inject commands or unusual file I/O initiated by these processes is critical.
