CVE-2026-21351

Current-user code execution via malicious-file use-after-free

Published Feb 10, 2026 · Updated Feb 10, 2026

Use-after-free in Adobe After Effects 25.6 and earlier allows context-dependent attackers to execute code when a victim opens a malicious file. Adobe has not published the affected component or the memory-lifetime operation that leaves a freed object accessible during file processing. Opening the crafted file is required, and successful exploitation runs code with the current user's privileges.
