CVE-2026-34264: CWE-204: Observable Response Discrepancy in SAP_SE SAP Human Capital Management for SAP S/4HANA
CVE-2026-34264 is a vulnerability in SAP Human Capital Management for SAP S/4HANA where authorization checks return specific messages that allow an authenticated user with low privileges to infer and enumerate information beyond their access rights. This leads to disclosure of sensitive information, impacting confidentiality. Integrity and availability are not affected. The vulnerability has a CVSS score of 6. 5, indicating medium severity. No official patch or remediation guidance is currently provided by the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability involves observable response discrepancies during authorization checks in SAP Human Capital Management for SAP S/4HANA. When a user with limited privileges attempts to access certain data, the system returns distinct messages that reveal whether the data exists or is accessible, enabling the user to guess and enumerate sensitive information beyond their authorized scope. The issue affects multiple versions of SAP Human Capital Management for SAP S/4HANA, including S4HCMRXX 100, 101, 102, and SAP_HRRXX 600, 604, 608. The vulnerability impacts confidentiality but does not affect integrity or availability. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, high confidentiality impact, and no impact on integrity or availability. No patch or official remediation level is currently documented.
Potential Impact
An authenticated user with low privileges can leverage the observable response discrepancy to enumerate and disclose sensitive information beyond their authorized access. This compromises confidentiality significantly. There is no impact on data integrity or system availability. No known exploitation in the wild has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, organizations should monitor SAP advisories for updates. No vendor-provided temporary or official fixes are currently documented. Access controls and monitoring of user activities may help reduce risk but are not direct mitigations for this specific vulnerability.
