CVE-2024-20729Public exploit

Code execution via freed Annot3D object reuse

Published Feb 15, 2024 · Updated Feb 13, 2025

Use-after-free in Adobe Acrobat and Acrobat Reader 20.005.30539 and 23.008.20470 and earlier allows attackers to execute code via a malicious PDF. Embedded JavaScript changes the page during an Annot3D zoom event, freeing an object that Reader later reuses without validating its lifetime and causing memory corruption. Exploitation requires a victim to open the crafted document; successful abuse runs code with the current user's privileges.
