CVE-2020-3716Network attack vector

Remote code execution via unsafe deserialization

Published Jan 29, 2020 · Updated Aug 4, 2024

Deserialization of untrusted data in Adobe Magento Open Source 2.3.3 and earlier allows remote attackers to execute arbitrary code. Adobe identifies the flaw only as unsafe deserialization and has not published the affected component, entry point, or operation that accepts attacker-controlled serialized data. Network access without authentication or user interaction is sufficient, and successful exploitation gives code execution in the application security context.
