CVE-2026-1248

Vulnerability

IBM Business Automation Workflow containers and traditional deployments may leak information about the database structure in error messages. This vulnerability affects both containerized and traditional deployments. The issue is present in versions prior to the April 2026 cumulative fix [1]. The error messages may reveal table names, column names, or other schema details.

Exploitation

An attacker could trigger error conditions that cause the application to return detailed database error messages. This requires network access to the application but no special privileges. The attacker does not need authentication if the error messages are exposed publicly. The exploitation involves sending crafted requests that result in database errors.

Impact

Successful exploitation allows an attacker to learn the database structure, including table and column names. This information can be used to plan further attacks, such as SQL injection or data theft. The impact is limited to information disclosure; no direct modification or access is achieved.

Mitigation

IBM has addressed this vulnerability in the April 2026 cumulative fix for IBM Business Automation Workflow. Apply the cumulative fix as described in the security bulletin [1]. For traditional deployments, ensure error handling is configured to not expose detailed database error messages to users. No workaround is available for container deployments other than applying the fix. The vulnerability is not listed in the KEV catalog.
