Technical details

An out-of-bounds write vulnerability (CWE-787) exists in Adobe After Effects versions 26.0, 25.6.4 and earlier. The flaw is triggered when the application processes a malformed file, leading to memory corruption. An attacker can leverage this to execute arbitrary code with the privileges of the current user. Exploitation requires local delivery of a malicious file and user interaction (opening the file). Adobe has addressed this issue in updated versions of the software.
