How to Fix CVE-2026-58230

To remediate this vulnerability, upgrade all affected @sap/approuter dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@sap/approuter fixed: 23.0.0 
npm install @sap/approuter@23.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @sap/approuter

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-58230, inspect your project dependencies using npm:

npm ls @sap/approuter

Analyze the terminal output to locate any version of @sap/approuter in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 23.0.0), your application is affected.

Note: The npm ls @sap/approuter command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In @sap/approuter, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

SAP Approuter does not sufficiently validate certain token content under specific configurations. An unauthenticated attacker could send a specially crafted token to cause sensitive credential material to be sent to an attacker-controlled destination. The attack complexity is high due to non-default preconditions required in the target environment. This results in a high impact on confidentiality and a low impact on integrity and availability.
