📦 What is this software?

⚠️ 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 persistent backdoor installation.

🟠

Likely Case

Local privilege escalation leading to malware installation, data exfiltration, or system disruption on the affected workstation.

🟢

If Mitigated

Limited impact with proper application sandboxing and user privilege restrictions, potentially only affecting the After Effects process.

🌐 Internet-Facing: LOW - Exploitation requires user interaction to open a malicious file, not directly exploitable over network.
🏢 Internal Only: MEDIUM - Internal users could be targeted via phishing or shared malicious project files, but requires user interaction.

🎯 Exploit Status

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

Exploitation requires user interaction (opening malicious file) and knowledge of file format manipulation. No public exploits known at this time.

Verify After Effects version is 25.2 or later, or 24.6.5 or later after applying update.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected After Effects crashes
  • Suspicious file opening events in application logs
  • Unusual process creation from After Effects

Network Indicators:

  • Unexpected outbound connections from After Effects process
