CVE-2026-27674: CWE-94: Improper Control of Generation of Code in SAP_SE SAP NetWeaver Application Server Java (Web Dynpro Java)
CVE-2026-27674 is a code injection vulnerability in SAP NetWeaver Application Server Java (Web Dynpro Java) version WD-RUNTIME 7.50. An unauthenticated attacker can supply crafted input that is interpreted by the application, causing it to reference attacker-controlled content. If a victim accesses the affected functionality, the attacker-controlled content could execute in the victim's browser, potentially compromising the session and allowing arbitrary client-side code execution. This impacts the confidentiality and integrity of the application but does not affect availability.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-27674) involves improper control of code generation (CWE-94) in SAP NetWeaver Application Server Java (Web Dynpro Java) WD-RUNTIME 7.50. An unauthenticated attacker can inject crafted input that the application interprets, leading to execution of attacker-controlled content in the victim's browser. This results in potential session compromise and arbitrary client-side code execution, impacting confidentiality and integrity. The CVSS 3.1 base score is 6.1, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, user interaction required, and scope changed.
Potential Impact
The vulnerability allows an attacker to execute arbitrary client-side code in the context of the victim's browser session, potentially compromising session confidentiality and integrity. There is no impact on system availability. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented. Until a patch is available, restrict access to the affected functionality and monitor for suspicious activity related to Web Dynpro Java applications.
