CVE-2026-27685
CWE-502Published: March 10, 2026· Updated: Mar 11, 2026
Official Description
SAP NetWeaver Enterprise Portal Administration is vulnerable if a privileged user uploads untrusted or malicious content that, upon deserialization, could result in a high impact on the confidentiality, integrity, and availability of the host system.
Technical Analysis
CVE-2026-27685 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
