CVE-2026-0497 Overview
SAP Product Designer Web UI of Business Server Pages contains a Missing Authorization vulnerability (CWE-862) that allows authenticated non-administrative users to access non-sensitive information they should not be able to view. This vulnerability results in a low impact on confidentiality, with no impact on integrity or availability of the application.
Critical Impact
Authenticated users can bypass authorization controls to access information outside their intended permission scope within SAP Product Designer Web UI.
Affected Products
- SAP Product Designer Web UI
- SAP Business Server Pages (BSP)

Technical Details for CVE-2026-0497
Vulnerability Analysis
This vulnerability stems from missing authorization checks (CWE-862) within the SAP Product Designer Web UI component of Business Server Pages. When authenticated users make requests to certain application endpoints, the application fails to properly validate whether the user has the necessary privileges to access the requested information. While the exposed data is classified as non-sensitive, the lack of proper authorization controls represents a deviation from the principle of least privilege.
The vulnerability is exploitable over the network and requires low privileges to exploit. No user interaction is required, making it relatively straightforward for any authenticated user to access information beyond their authorized scope. The scope remains unchanged, meaning the vulnerable component and impacted component are the same.
Root Cause
The root cause of this vulnerability is missing authorization (CWE-862) in the SAP Product Designer Web UI. The application fails to perform adequate authorization checks before returning information to authenticated users, allowing those with limited privileges to access data that should be restricted to higher privilege levels or other user groups.
Attack Vector
The attack vector for CVE-2026-0497 is network-based, requiring the attacker to be an authenticated user of the SAP Business Server Pages application. An attacker would need valid credentials to access the SAP environment, but once authenticated, they can exploit the missing authorization checks to retrieve information beyond their assigned permissions.
The exploitation process involves sending crafted requests to the vulnerable SAP Product Designer Web UI endpoints. Since no user interaction is required and attack complexity is low, this vulnerability can be exploited reliably by any authenticated user with knowledge of the vulnerable functionality.
Detection Methods for CVE-2026-0497
Indicators of Compromise
- Unusual access patterns to SAP Product Designer Web UI endpoints by non-administrative users
- Log entries showing users accessing resources outside their normal permission boundaries
- Increased query volume from specific user accounts to information retrieval endpoints
Detection Strategies
- Review SAP security audit logs for unauthorized access attempts to Product Designer components
- Implement monitoring for authentication events followed by unusual resource access patterns
- Configure SAP Solution Manager to alert on anomalous user behavior within BSP applications
Monitoring Recommendations
- Enable comprehensive audit logging for SAP Business Server Pages applications
- Monitor user access patterns and flag deviations from baseline behavior
- Implement real-time alerting for access to sensitive Product Designer endpoints by non-admin users
How to Mitigate CVE-2026-0497
Immediate Actions Required
- Apply the security patch referenced in SAP Note #3677111
- Review user permissions within SAP Product Designer Web UI and enforce least privilege
- Audit current access logs to identify any potential unauthorized information access
Patch Information
SAP has released a security update to address this vulnerability. Organizations should apply the patch documented in SAP Note #3677111. Additional information is available through the SAP Security Patch Day Update. Administrators should test the patch in a non-production environment before deploying to production systems.
Workarounds
- Restrict network access to SAP Product Designer Web UI to only authorized IP ranges
- Implement additional application-layer authorization controls where possible
- Review and tighten SAP role-based access controls for BSP applications
- Consider temporary restriction of non-essential user access until patching is complete
# Configuration example - Review SAP authorization roles
# Access SAP transaction PFCG to review role authorizations
# Ensure Product Designer access is properly restricted
# Check current role assignments for BSP components
# Transaction: SU01 - User Maintenance
# Review authorizations related to Product Designer objects
