CVE-2023-48633

Code execution via stale AEP parser object

Published Dec 13, 2023 · Updated Aug 2, 2024

Use-after-free in Adobe After Effects 24.0.3 and earlier and 23.6.0 and earlier allows remote attackers to execute code via an AEP file. The AEP parser operates on an object without first validating that the object still exists, leaving a freed object available for reuse. Exploitation requires the victim to open the file or visit a malicious page, and resulting code runs with the current process's privileges.
