CVE-2026-0504 in Identity Management
Summary
by MITRE • 01/13/2026
Due to insufficient input handling, the SAP Identity Management REST interface allows an authenticated administrator to submit specially crafted malicious REST requests that are processed by JNDI operations without adequate input neutralization. This may lead to limited disclosure or modification of data, resulting in low impact on confidentiality and integrity, with no impact on application availability.

The vulnerability identified as CVE-2026-0504 resides within the SAP Identity Management system's REST interface, representing a critical concern for organizations relying on proper identity and access management controls. This issue manifests through inadequate input validation mechanisms that fail to properly sanitize user-supplied data before processing within JNDI (Java Naming and Directory Interface) operations. The vulnerability specifically affects authenticated administrators who possess the necessary privileges to interact with the REST API endpoints, creating a scenario where legitimate administrative access can be exploited for unauthorized data manipulation.
The technical flaw stems from the system's failure to implement proper input neutralization techniques when processing REST requests that involve JNDI operations. JNDI is a Java API used for accessing naming and directory services, and when improperly handled, it can become a vector for various attack vectors including LDAP injection and remote code execution. The insufficient input handling allows maliciously crafted requests to bypass normal validation checks, enabling attackers to inject malicious JNDI references that can be resolved by the system. This weakness aligns with CWE-74 standards related to improper neutralization of special elements used in data queries, specifically targeting the JNDI injection category. The vulnerability operates under the principle that when user input is directly used in JNDI lookups without proper sanitization, the system becomes susceptible to arbitrary code execution or data manipulation through controlled directory service interactions.
From an operational impact perspective, the vulnerability presents a low but significant risk to the confidentiality and integrity of the affected system's data. While the attack requires authentication and administrative privileges, the potential consequences extend beyond simple data theft to include unauthorized modifications of identity management configurations and user access controls. The limited disclosure or modification capabilities suggest that attackers cannot completely compromise the system but can manipulate specific data elements within the identity management domain. This vulnerability falls under the ATT&CK framework's technique T1078 for Valid Accounts and T1566 for Phishing, as it exploits legitimate administrative credentials to perform unauthorized operations within the system. Organizations may experience indirect impacts through compromised identity data that could affect access to other systems or lead to privilege escalation in interconnected environments.
The mitigation strategies for CVE-2026-0504 should focus on implementing comprehensive input validation and sanitization measures within the REST interface. Organizations must ensure that all user-supplied data is properly validated and neutralized before being processed in JNDI operations, with particular attention to preventing the injection of malicious directory service references. The implementation of proper access controls and least privilege principles should be reinforced, ensuring that administrative privileges are strictly monitored and that any suspicious activities are immediately flagged. Additionally, organizations should consider implementing network segmentation to limit access to the identity management system and deploy monitoring solutions that can detect anomalous REST API usage patterns. The remediation efforts should align with industry best practices outlined in the OWASP Top Ten and NIST Cybersecurity Framework, particularly focusing on input validation controls and secure coding practices. Regular security assessments and penetration testing should be conducted to verify the effectiveness of implemented controls and to identify any potential bypass mechanisms that attackers might employ to exploit similar vulnerabilities.
