📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise with attacker gaining full control over the workstation, potentially leading to data theft, ransomware deployment, or lateral movement within the network.

🟠

Likely Case

Local privilege escalation or arbitrary code execution in the context of the current user, allowing file system access, credential harvesting, and persistence mechanisms.

🟢

If Mitigated

Limited impact due to proper application sandboxing, limited user privileges, and network segmentation preventing lateral movement.

🌐 Internet-Facing: LOW - Exploitation requires local access or user interaction with malicious files, not directly exploitable over network.
🏢 Internal Only: MEDIUM - Risk exists for workstations with vulnerable software, particularly if users open untrusted project files or media content.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires user interaction (opening malicious file). No public exploit code available at time of advisory.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 14.3 or later

Application control

windows

Use application whitelisting to restrict execution of Premiere Pro to trusted locations only

🧯 If You Can't Patch

  • Isolate affected systems from critical network segments and limit internet access
  • Implement strict user privilege controls and run Premiere Pro with minimal necessary permissions

🔍 How to Verify

Check if Vulnerable:

Check Premiere Pro version via Help > About Premiere Pro. If version is 14.2 or earlier, system is vulnerable.

Check Version:

On Windows: Check registry at HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Premiere Pro\14.0\Version. On macOS: Check /Applications/Adobe Premiere Pro CC 2020/Adobe Premiere Pro CC 2020.app/Contents/Info.plist

Verify Fix Applied:

Verify version is 14.3 or later in Help > About Premiere Pro and check Creative Cloud shows no available updates.
