CVE-2026-80161

Acrobat Reader | Access of Resource Using Incompatible Type ('Type Confusion') (CWE-843)

Published Sep 8, 2026 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed

Description

Acrobat Reader is affected by an Access of Resource Using Incompatible Type ('Type Confusion') vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability to execute arbitrary code. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Analysis

Technical impact

Adobe Acrobat and Acrobat Reader contain a type confusion flaw that permits arbitrary code execution when a user opens a specially crafted file. The vulnerability can be leveraged by an attacker to run code with the privileges of the current user, potentially compromising the device and user data.

Affected Systems

Adobe releases affected by this flaw include Acrobat 2024, Acrobat Reader, and Adobe Acrobat. No specific version numbers are listed in the CNA data; all current releases are potentially vulnerable until a patch is applied.

Risk and Exploitability

The severity score of 7.8 indicates a high risk of exploitation. The EXSS score is not available, and the vulnerability is not listed in CISA’s KEV catalog. Exploitation requires the victim to interact by opening a malicious file, making user awareness a critical defense factor. If exploited, the attacker can achieve full code execution under the victim’s user context.
