CVE-2026-27674 — Sap Netweaver Application Server Java security vulnerability

Medium CVSS 6.1

Due to a Code Injection vulnerability in SAP NetWeaver Application Server Java (Web Dynpro Java), an unauthenticated attacker could supply crafted input that is interpreted by the application and causes it to reference attacker-controlled content. If a victim accesses the affected functionality, that attacker-controlled content could be executed in the victim�s browser, potentially resulting in session compromise. This could allow the attacker to execute arbitrary client-side code, impacting the confidentiality and integrity of the application, with no impact to availability.

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
