Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate @sap/xssec in package.jsonOpen your project's package.json file and search for '@sap/xssec' in the dependencies or devDependencies section. Note the version number listed next to it.Affected if The version shown is less than 3.6.0 (for example, 3.5.0, 3.4.0, or any version starting with 3.x.y where y is less than 6, or any 2.x version)
-
Verify installed version with npmRun the command 'npm list @sap/xssec' in your project root directory to see the currently installed version, including any nested dependencies.Affected if The output shows a version number lower than 3.6.0
-
Check package-lock.json for pinned versionOpen the package-lock.json file in your project and search for '@sap/xssec'. The 'version' field indicates the exact installed version.Affected if The version field shows a version lower than 3.6.0
-
Confirm dependency tree if using transitive dependenciesRun 'npm list @sap/xssec --all' to see if @sap/xssec is a transitive dependency pulled in by another package, and note its version.Affected if Any instance of @sap/xssec in the tree is below version 3.6.0
If the installed @sap/xssec library version is below 3.6.0, your environment is affected by this privilege escalation vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.6.0
Upgrade @sap/xssec to version 3.6.0 or later. Review application authorization logic after the upgrade to confirm the privilege escalation vector is remediated.
@sap/xssec version 3.6.0 or later
- Check the current version of @sap/xssec in your project dependencies (e.g., in package.json or package-lock.json)
- Upgrade @sap/xssec to version 3.6.0 or later using your package manager (npm install @sap/xssec@^3.6.0 or yarn upgrade @sap/xssec@^3.6.0)
- Run your test suite to verify the upgrade does not break existing functionality
- Deploy the updated application
