Full Report
Multiple vulnerabilities have been discovered in Adobe products, the most severe of which could allow for arbitrary code execution.Adobe After Effects is a digital effects, motion graphics, and compositing application.Adobe Commerce is a composable ecommerce solution that lets you quickly create global, multi-brand B2C and B2B experiences all from one cloud-native platform.Adobe Connect is a secure, highly customizable web conferencing and virtual training platform used for webinars, online meetings, and e-learning.Adobe Media Encoder is a transcoding and rendering application that lets you deliver audio and video files in a broad variety of formats.Adobe Premiere Pro is a subscription-based timeline video editing software for film, TV, and web.Adobe Substance 3D is a suite of tools for creating 3D content, including modeling, texturing, and rendering.Content Authenticity SDK contains Rust and JavaScript libraries, enabling web pages to read, validate, create, and sign manifest data, and embed it in supported asset files.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.

- Content Authenticity SDK (JS SDK @contentauth/sdk-js; Rust SDK c2pa-v0.80.1)
## Vulnerability Description
Multiple security flaws exist across the Adobe ecosystem. The most critical involve memory corruption issues (Buffer Overflows and Out-of-bounds Writes) in video and graphics tools, which can be triggered when the application processes specially crafted files. In **Adobe Commerce**, vulnerabilities include SSRF, Path Traversal, and Incorrect Authorization, which could lead to unauthorized data access or resource exhaustion. **Adobe Connect** is specifically noted for a Deserialization of Untrusted Data flaw, a common vector for remote code execution.
## Exploitation
- **Status:** Not currently exploited in the wild; no public PoC reported at this time.
- **Complexity:** Medium (Often requires user interaction, e.g., opening a malicious file).
- **Attack Vector:** Network (Commerce/Connect) | Local (Creative Cloud/Substance 3D via file opening).
## Impact
- **Confidentiality:** High (Ability to view sensitive data).
- **Integrity:** High (Arbitrary code execution; ability to install programs or modify data).
- **Availability:** High (Ability to delete data or crash systems).
## Remediation
### Patches
Adobe has released updates to address these vulnerabilities. Users should update to the following versions or newer:
- **After Effects:** 25.6.5 / 26.1
- **Adobe Commerce:** Apply latest security patches (e.g., p18, p17, etc., based on release branch).
- **Adobe Connect:** Update to latest desktop version via the official portal.
- **Illustrator:** 29.8.7 / 30.4
- **Premiere Pro/Media Encoder:** 25.6.5 / 26.0.3
### Workarounds
- **Least Privilege:** Operate systems using accounts with non-administrative rights to limit the impact of code execution.
- **File Sanitization:** Avoid opening untrusted project files or assets from unknown sources.
## Detection
- **Indicators of Compromise:** Unusual outbound network traffic from web servers (SSRF), unauthorized new admin accounts in Magento/Commerce, or unexpected application crashes when opening media files.
- **Detection Methods:** Use File Integrity Monitoring (FIM) on web server directories and utilize Endpoint Detection and Response (EDR) to monitor for suspicious child processes spawned by Adobe applications (e.g., `cmd.exe` spawned by `AfterFX.exe`).
