💻 Affected Systems
- Adobe After Effects
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control of the victim's computer, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Malicious actors send phishing emails with crafted After Effects project files, leading to malware installation when opened by targeted users.
If Mitigated
With proper security controls, the impact is limited to the user's workstation without lateral movement, and security software may detect the malicious file.
🎯 Exploit Status
Exploitation requires user interaction (opening a malicious file). No public exploit code has been reported as of the advisory date.
