Technical details
A use-after-free vulnerability exists in Adobe After Effects where an application function attempts to access memory after it has been freed, potentially allowing execution of attacker-controlled code. The vulnerability affects versions 25.6 and earlier. Exploitation requires user interaction—specifically, the victim must open a malicious file (such as a project file) in After Effects. When triggered, an attacker gains code execution in the context of the current user. A patch or update addressing this issue is likely available from Adobe.
