CVE-2026-58230 · Severity: high · CVSS 7 · Published 2026-08-11

SAP Approuter is a routing and application gateway used in SAP's cloud infrastructure. The application does not properly validate token content in certain configurations, allowing an unauthenticated attacker to send crafted tokens that cause sensitive credentials to be leaked to attacker-controlled servers. This could expose database passwords, API keys, and other authentication material used by backend systems.

Technologies: [@sap/approuter (npm)](https://junglewise.ai/threats/technologies/sap-approuter). Vendors: [npm](https://junglewise.ai/threats/vendors/npm).

## Technical details

The vulnerability is rooted in inadequate token validation in SAP Approuter, specifically related to URL redirection (CWE-601). An unauthenticated attacker can craft a malicious token that, under non-default configurations, causes the application to redirect sensitive credential material (such as authentication tokens, API keys, or session data) to an attacker-controlled endpoint. The attack vector is network-based and requires no user interaction, but attack complexity is rated high due to environmental preconditions (non-standard configuration) that must be present. An attacker exploiting this vulnerability would achieve unauthorized access to confidential credential material. Versions prior to 23.0.0 are affected; SAP released patch version 23.0.0 on August 11, 2026.
