CVE-2024-30305

Arbitrary code execution via stale AcroForm object

Published May 2, 2024 · Updated Aug 2, 2024

Use-after-free in Adobe Acrobat Reader 20.005.30539 and 23.008.20470 and earlier allows remote attackers to execute arbitrary code. AcroForm handling operates on an object without validating that it still exists, leaving a freed object available for reuse. A victim must visit a malicious page or open a malicious file; successful exploitation runs code in the current user's process context.
