Full Report
Multiple vulnerabilities have been discovered in Adobe products, the most severe of which could allow for arbitrary code execution.Adobe Acrobat Reader is a free, widely used software application from Adobe that allows users to view, print, sign, share, and annotate PDF documents.Adobe InDesign is desktop publishing software used to create, pre-flight, and publish professional page layouts for print and digital media.Adobe InCopy is professional writing and editing software that integrates directly with Adobe InDesign to enable collaborative workflows between editors, copywriters, and designers.Adobe Experience Manager (AEM) Screens is a cloud-based digital signage solution that extends AEM’s content management capabilities to physical, in-venue displays.Adobe FrameMaker is a powerful, industry-standard desktop publishing software designed for authoring, managing, and publishing complex, long-form technical documentation.Adobe Connect is a secure, highly customizable web conferencing and virtual training platform used for webinars, online meetings, and e-learning.Adobe ColdFusion is a commercial rapid web application development platform and server-side technology used to build, deploy, and manage dynamic websites and internet applications.Adobe Bridge is a free, powerful digital asset management (DAM) application designed to organize, browse, locate, and view creative assets.Adobe Photoshop is software for raster image editing, graphic design, and digital art.The Adobe DNG Software Development Kit (SDK) is a set of tools and libraries for developers to read, write, and manipulate Digital Negative (DNG) files, an open, lossless raw image format.Adobe Illustrator is vector graphics software used by designers to create scalable, high-resolution artwork such as logos, icons, illustrations, and typography.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
# Vulnerability: Multiple Adobe Product Flaws Facilitate Arbitrary Code Execution
## CVE Details
- **CVE IDs:** Primary examples include CVE-2026-34622, CVE-2026-34626 (Acrobat); CVE-2026-27283, CVE-2026-27291 (InDesign); CVE-2026-27288 (AEM); CVE-2026-34615, CVE-2026-34617 through CVE-2026-34625.
- **CVSS Score:** Not explicitly listed per CVE, but categorized as **Critical/High Risk**.
- **CWE:** CWE-1321 (Prototype Pollution), CWE-416 (Use After Free), CWE-125 (Out-of-bounds Read), CWE-787 (Out-of-bounds Write), CWE-122 (Heap-based Buffer Overflow), CWE-79 (Stored XSS).
## Affected Systems
- **Adobe Acrobat / Reader:** DC 26.001.21411 and earlier; Acrobat 2024 (Win: 24.001.30362; Mac: 24.001.30360) and earlier.
- **Adobe InDesign / InCopy:** ID21.2 and ID20.5.2 and earlier.
- **Adobe Experience Manager (AEM) Screens:** 6.5 SP 24 and earlier; FP 11.7 and earlier.
- **Adobe FrameMaker:** 2022 Release Update 8 and earlier.
- **Adobe Connect:** 12.10 and earlier; Desktop App 2025.3 and earlier.
- **Adobe ColdFusion:** 2025 Update 6 and earlier; 2023 Update 18 and earlier.
- **Adobe Bridge:** 15.1.4 (LTS) and earlier; 16.0.2 and earlier.
- **Adobe Photoshop:** 2026 version 27.4 and earlier.
- **Adobe Illustrator:** 2025 (29.8.5) and 2026 (30.2) and earlier.
- **Adobe DNG SDK:** 1.7.1 build 2502 and earlier.
## Vulnerability Description
This advisory covers a wide range of memory corruption and logic flaws across the Adobe creative and enterprise suite. Key technical issues include:
- **Memory Corruption:** Use-after-free, heap overflows, and out-of-bounds writes allow attackers to overwrite memory locations to redirect application flow.
- **Object Manipulation:** Prototype Pollution in Acrobat Reader allows for the modification of object attributes, leading to code execution.
- **Web Vulnerabilities:** Stored XSS in AEM Screens allows for persistent malicious script injection.
## Exploitation
- **Status:** Not currently reported as exploited in the wild.
- **Complexity:** Medium (typically requires a victim to open a maliciously crafted file).
- **Attack Vector:** Local (via malicious PDF/media files) or Network (for web-based products like ColdFusion/AEM).
## Impact
- **Confidentiality:** High (Attacker can view all data accessible by the user).
- **Integrity:** High (Attacker can install programs, modify or delete critical data).
- **Availability:** High (Attacker can delete data or crash systems).
## Remediation
### Patches
Adobe has released updates to address these vulnerabilities. Users should upgrade to the following or later:
- **Acrobat/Reader:** Version 26.001.21412+ or 2024.001.30363+
- **InDesign/InCopy:** Versions exceeding 21.2/20.5.2.
- **ColdFusion:** 2025 Update 7+ / 2023 Update 19+.
- **Photoshop/Illustrator:** Update via Creative Cloud to the latest 2026 iterations.
### Workarounds
- Apply the **Principle of Least Privilege (PoLP)**: Ensure users operate with standard accounts rather than administrative rights to limit the scope of a successful "Arbitrary Code Execution."
- Block suspicious file attachments at the email gateway.
## Detection
- Monitor for unusual process spawning from Adobe binaries (e.g., `Acrobat.exe` launching `cmd.exe` or `powershell.exe`).
- Use EDR tools to detect heap-spray patterns or unauthorized memory writes associated with the listed CWE types.
