CVE-2026-103094 in AI Platform
Summary
by MITRE • 10/29/2026
ServiceNow has remediated an information disclosure vulnerability that was identified in the ServiceNow AI Platform. This vulnerability could cause a user's plaintext password to be persisted in a system table, potentially exposing that password to a user who otherwise would not be entitled to view it.
ServiceNow remediated the vulnerability through security updates that address the unintended persistence of plaintext credentials. We are not currently aware of malicious exploitation against ServiceNow instances. We recommend customers promptly apply appropriate updates or upgrade to a patched release if they have not already done so.

An information disclosure vulnerability was identified within the ServiceNow AI Platform, specifically involving the unintended persistence of plaintext credentials in system tables. This flaw allowed for the storage of user passwords in clear text rather than utilizing secure hashing mechanisms or encrypted storage formats typically required by modern security standards. The presence of these plaintext values in database structures creates a significant risk vector where sensitive authentication data becomes accessible to individuals who should not have such privileges, thereby compromising the confidentiality and integrity of user accounts across affected instances.
The technical nature of this flaw centers on improper credential handling during specific operations within the AI Platform module. When users interact with certain features or when system processes update account information, the application logic failed to mask or hash the password before writing it to persistent storage layers. This results in sensitive authentication material being written directly into database tables that may be queried by other components of the platform or accessed through administrative interfaces if proper access controls are not strictly enforced. Such behavior violates fundamental principles of secure software design regarding data protection and minimizes the security boundary against internal threats or lateral movement within compromised environments.
From an operational perspective, this vulnerability poses a severe risk to organizational security postures. If an attacker gains low-level access to the ServiceNow instance through any other vector, such as exploiting a separate cross-site scripting flaw or gaining unauthorized API access, they could query these system tables to retrieve plaintext passwords. These credentials can then be used for credential stuffing attacks against external services if users reuse passwords, or for privilege escalation within the platform itself. The impact extends beyond immediate account compromise, potentially leading to broader data breaches and regulatory non-compliance due to the exposure of personally identifiable information and authentication secrets.
This incident aligns with Common Weakness Enumeration category CWE-256, which covers the storage of passwords in a recoverable format, as well as CWE-319 regarding cleartext transmission or storage of sensitive data. In terms of adversary tactics, this vulnerability facilitates techniques associated with ATT&CK ID T1078, specifically valid accounts and potentially T1552 if attackers leverage these credentials to access additional resources without detection. The ability to extract plaintext passwords significantly lowers the barrier for lateral movement and persistent access within enterprise environments that rely on ServiceNow for IT service management and other critical operations.
ServiceNow has addressed this issue through security updates designed to prevent the unintended persistence of plaintext credentials in system tables. These patches ensure that password data is handled according to industry best practices, likely involving hashing or encryption before storage. Organizations are strongly advised to apply these security updates immediately if they have not already done so. Given that there is currently no evidence of malicious exploitation against ServiceNow instances, the primary goal is preventive hardening rather than incident response for active breaches. However, administrators should also review access logs and implement strict role-based access controls on system tables to mitigate any residual risk from previous exposure periods. Regular audits of credential storage mechanisms and adherence to least privilege principles remain essential components of a robust security strategy in conjunction with timely patch management.
