Impact

An injection flaw in IBM API Connect 12.1.0.0 through 12.1.1.2 permits an authenticated attacker to retrieve data that belongs to other tenants. The vulnerability arises because user input incorporated into database queries is not properly neutralized, allowing the query to return records that the authenticated user should not be able to see.

Affected Systems

The affected products are IBM API Connect 12.1.0.0 and 12.1.1.2. IBM recommends upgrading to version 12.1.1.3 to remediate the issue.

Risk and Exploitability

The CVSS base score of 7.7 indicates a high severity. EPSS is not available and the vulnerability is not listed in the KEV catalogue. Exploitation requires an authenticated session; an attacker who possesses valid user credentials can exploit the vulnerable endpoint to construct a query that returns data from other tenants, enabling unauthorized disclosure of sensitive information.
