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 powerful asset management tool that allows creative professionals to preview, organize, edit, and publish multiple creative assets efficiently across the Creative Cloud ecosystem.Adobe Format Plugins are software add-ons used by Adobe applications to handle file formats, convert data types, and process specific file structures safely.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 Vulnerabilities in Adobe Products (Bridge and Format Plugins)
## CVE Details
- **CVE IDs:**
- CVE-2026-48372 (Most Severe - Adobe Format Plugins)
- CVE-2026-48374, CVE-2026-48390, CVE-2026-48391, CVE-2026-48392, CVE-2026-48393, CVE-2026-48394, CVE-2026-48395, CVE-2026-48396 (Adobe Bridge)
- **CVSS Score:** Not explicitly listed in source, but rated as **High Risk** by MS-ISAC.
- **CWE:**
- CWE-122 (Heap-based Buffer Overflow)
- CWE-787 (Out-of-bounds Write)
- CWE-427 (Untrusted Search Path)
- CWE-285 (Incorrect Authorization)
- CWE-22 (Path Traversal)
## Affected Systems
- **Products:** Adobe Bridge, Adobe Format Plugins
- **Versions:**
- Adobe Bridge 15.1.6 (LTS) and earlier versions
- Adobe Bridge 16.0.5 and earlier versions
- Adobe Format Plugins 2026.05 and earlier versions
- **Configurations:** Systems where users operate with Administrative privileges face the highest risk of full system compromise.
## Vulnerability Description
Multiple flaws exist in the way Adobe Bridge and its format plugins process data and handle file paths. The most critical issue is a **Heap-based Buffer Overflow** in Adobe Format Plugins, which can be triggered when the application handles specifically crafted file structures. In Adobe Bridge, vulnerabilities include **Out-of-bounds Writes**, **Path Traversal**, and **Untrusted Search Path** issues. Collectively, these flaws allow an attacker to bypass security boundaries or corrupt memory to execute arbitrary code.
## Exploitation
- **Status:** Not exploited in the wild (at time of advisory).
- **Complexity:** Medium (Generally requires a user to open a malicious file).
- **Attack Vector:** Local (Client-side exploitation via malicious asset/file ingestion).
## Impact
- **Confidentiality:** High (Attacker can view all data accessible to the user).
- **Integrity:** High (Attacker can change or delete data and install programs).
- **Availability:** High (Attacker can delete data or crash the system).
## Remediation
### Patches
Adobe has released stable channel updates to address these vulnerabilities. Users should update to versions newer than:
- Adobe Bridge 15.1.6 (LTS)
- Adobe Bridge 16.0.5
- Adobe Format Plugins 2026.05
### Workarounds
- **Principle of Least Privilege:** Operate systems using non-administrative accounts to limit the impact of code execution.
- **User Education:** Caution users against opening unsolicited or suspicious files (e.g., assets from untrusted sources) within Adobe Bridge.
## Detection
- **Indicators of Compromise:** Monitor for unusual child processes spawning from `Bridge.exe` or unauthorized modifications to system directories and registry keys.
- **Detection Methods:** Utilize SCAP-compliant vulnerability scanners to identify out-of-date Adobe binaries. Monitor endpoint logs for Technique T1203 (Exploitation for Client Execution).
