Deeper analysis

Acrobat Reader DC versions 22.001.20085 and earlier, 20.005.3031x and earlier, and 17.012.30205 and earlier contain a use-after-free vulnerability (CWE-416) in the handling of acroform events. The flaw can lead to arbitrary code execution in the context of the current user and carries a CVSS 3.0 score of 7.8.

An attacker can trigger the issue only by convincing a victim to open a malicious PDF file. Successful exploitation grants the attacker the ability to execute arbitrary code locally with the privileges of the logged-in user.

Adobe’s security advisory APSB22-16, referenced at helpx.adobe.com, addresses the affected Acrobat Reader DC releases and supplies the corresponding patches and mitigation guidance.

The associated EPSS score has remained flat at a peak of 0.1143 since disclosure, indicating no material increase in observed exploitation interest.
