CVE-2022-28847
📋 TL;DR
CVE-2022-28847 is an out-of-bounds write vulnerability in Adobe Bridge that allows arbitrary code execution when a user opens a malicious file. This affects Adobe Bridge version 12.0.1 and earlier. Attackers can gain the same privileges as the current user through crafted files.
💻 Affected Systems
- Adobe Bridge
📦 What is this software?
Bridge by Adobe
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining the same privileges as the current user, potentially leading to data theft, ransomware deployment, or lateral movement.
Likely Case
Local privilege escalation leading to malware installation, data exfiltration, or persistence mechanisms being established on the affected system.
If Mitigated
Limited impact with proper application sandboxing, least privilege principles, and file execution restrictions in place.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) but the vulnerability itself is straightforward to exploit once file is opened.

🔧 Temporary Workarounds
Restrict file types
allConfigure system to only allow trusted file types to open with Adobe Bridge
Windows: Use Group Policy to restrict file associations
macOS: Use parental controls or MDM to restrict application file associations
Application control
allUse application whitelisting to prevent execution of unauthorized files
Windows: Configure AppLocker or Windows Defender Application Control
macOS: Use Gatekeeper and System Integrity Protection
🧯 If You Can't Patch
- Implement strict file execution policies and user training about opening untrusted files
- Use application sandboxing or virtualization for Adobe Bridge usage
