Technical details

An integer overflow or wraparound vulnerability (CWE-190) exists in Adobe After Effects versions 26.0, 25.6.4 and earlier. The flaw is triggered when the application processes a specially crafted file, leading to memory corruption. An attacker can leverage this to achieve arbitrary code execution in the context of the current user. Exploitation requires local access to deliver the file and relies on user interaction (opening the malicious file). Adobe has addressed this in newer versions, such as 25.6.5.
