CVE-2026-92759 in SecObserve
Summary
by MITRE • 09/16/2026
SecObserve versions before 1.59.1 contain an information disclosure vulnerability in the ApiConfigurationSerializer that fails to strip the basic_auth_password field from API configuration responses. View-only product members can retrieve the decrypted basic-auth password of configured scanner or integration service accounts through standard REST endpoints.

SecObserve versions prior to 1.59.1 are affected by a critical information disclosure vulnerability located within the ApiConfigurationSerializer component. This flaw stems from an improper implementation of data serialization logic, specifically regarding how API configuration objects are converted into JSON responses for client consumption. The core technical deficiency lies in the failure to exclude sensitive credential fields during this transformation process. In secure software design, serializers must explicitly filter out or mask high-sensitivity attributes such as passwords before they are transmitted over network interfaces. However, in this instance, the serializer includes the basic_auth_password field intact within the response payload sent by standard REST endpoints. This represents a fundamental breach of the principle of least privilege and proper data handling practices, where sensitive authentication material is exposed to contexts that do not require it for operational functionality.
The operational impact of this vulnerability is severe due to its low barrier to exploitation and high potential consequence. Any user authenticated with view-only permissions can exploit this flaw by issuing standard HTTP GET requests to the relevant API endpoints associated with scanner or integration service configurations. Because these users typically possess limited privileges intended only for monitoring system status rather than modifying settings, they are often not subject to the same rigorous access controls as administrators. By leveraging their existing read-access rights, an attacker can retrieve the plaintext passwords of configured scanner accounts and third-party integration services. This effectively bypasses administrative security boundaries, allowing lower-privileged users to escalate their influence by obtaining credentials that grant broader system access or control over external integrations.
From a classification perspective, this vulnerability aligns with CWE-200: Information Exposure, specifically falling under the sub-category of sensitive information exposure in API responses. It also maps directly to MITRE ATT&CK technique T1530: Data from Cloud Storage Object or Local System Files if we consider the configuration database as a storage object, but more accurately it fits within T1078: Valid Accounts when considering how these stolen credentials can be used for lateral movement or privilege escalation. The vulnerability highlights a common pitfall in modern web application development where serialization libraries are configured with default behaviors that do not account for security-sensitive fields unless explicitly instructed to ignore them. This lack of explicit exclusion logic allows sensitive data to leak through standard communication channels intended for non-privileged users.
Mitigation strategies must focus on immediate patching and architectural review. The primary remediation is to upgrade SecObserve to version 1.59.1 or later, where the ApiConfigurationSerializer has been corrected to strip the basic_auth_password field from all API responses regardless of user role. In addition to applying this software update, organizations should conduct a thorough audit of their API serialization configurations across other modules to ensure no similar oversights exist elsewhere in the application codebase. It is also recommended to implement strict output encoding and filtering policies that treat all credential fields as sensitive by default. Furthermore, security teams should rotate any passwords exposed through this vulnerability immediately upon discovery, assuming compromise has occurred given the ease of access for view-only users. Implementing comprehensive API gateway logging can help detect anomalous retrieval patterns of configuration data in future deployments.
