Adobe Acrobat Reader Annotation Use-After-Free Remote Code Execution
CVE-2026-47918 is a use-after-free vulnerability in Adobe Acrobat Reader DC affecting versions 24.001.30365, 26.001.21651, and earlier. The flaw exists in the handling of Annotation objects, where the application fails to properly validate an object's continued existence before performing operations on it. This memory-safety issue can be triggered by a specially crafted malicious file, and reporting also indicates exploitation may occur when a target visits a malicious page. Successful exploitation can lead to arbitrary code execution in the context of the current user/process.
