CVE-2026-80161

Code execution via malicious-file type confusion

Published Sep 8, 2026 · Updated Sep 10, 2026

Type confusion in Adobe Acrobat and Reader allows attackers to execute code through a malicious PDF on affected desktop releases. The flaw accesses a resource through an incompatible type, but Adobe has not disclosed the affected parser, object type, or erroneous cast. Exploitation requires a victim to open the file, and successful code runs with the victim's current-user privileges.
