CVE-2026-34263
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDue to improper Spring Security configuration, SAP Commerce Cloud allows an unauthenticated user to perform malicious input injection, resulting in arbitrary server-side code execution, leading to high impact on Confidentiality, Integrity, and Availability of the application.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceImproper Spring Security configuration in SAP Commerce Cloud allows unauthenticated attackers to inject malicious input, leading to arbitrary server-side code execution. This critical flaw stems from missing or inadequate access controls in the Spring Security layer, enabling remote code execution without any authentication.

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.
-
Identify SAP Commerce Cloud installation and versionLocate the SAP Commerce Cloud installation directory and check for version information files (such as version.txt, manifest.json, or build information in the platform folder). Compare the installed version to any available version documentation.Affected if The installed version is unpatched and within the affected version range for this CVE.
-
Locate Spring Security configuration filesSearch for Spring Security configuration files in the SAP Commerce Cloud installation, typically found under /hybris/config/ or /bin/custom/ with patterns such as spring-security*.xml, SecurityConfig.java, or application.properties/yaml files containing security settings.Affected if Missing or improperly configured Spring Security XML or Java config files are present that do not enforce authentication on endpoints.
-
Inspect security filter chain configurationExamine the Spring Security filter chain configuration for URL patterns and their required authentication status. Look for sections defining <http> or SecurityFilterChain beans that specify which endpoints require authentication (formLogin, httpBasic, or other auth mechanisms).Affected if Sensitive endpoints or APIs are mapped to permitAll() or have no authentication requirement defined, allowing unauthenticated access.
-
Verify endpoint access control rulesReview the access control definitions for all exposed endpoints, checking that protected resources have proper role-based or authentication requirements. Look for any explicitly permitted paths that should require auth.Affected if Any administrative, API, or sensitive endpoints are accessible without authentication due to misconfigured access rules.
If SAP Commerce Cloud is running with Spring Security configurations that permit unauthenticated access to sensitive endpoints or APIs, the environment is affected by this CVE.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataReview and properly configure Spring Security settings in SAP Commerce Cloud, ensuring all endpoints require appropriate authentication and authorization; implement strict input validation and restrict access to sensitive endpoints.
