CVE-2026-0503: Due to missing authorization check in the SAP ERP Central Component (SAP ECC) and SAP S/4HANA (SAP EHS Management), an attacker could extract hardcoded clear-text credentials and bypass the password authentication check by manipulating user parameters. Upon successful exploitation, the attacker can access, modify or delete certain change pointer information within EHS objects in the application which might further affect the subsequent systems. This vulnerability leads to a low impact on confidentiality and integrity of the application with no affect on the availability.
The exploitability of CVE-2026-0503 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2026-0503 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-0503, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-0503, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
