AI Analysis

Impact

Cross-site scripting in IBM API Connect enables an authenticated user to run arbitrary JavaScript within the web interface, potentially altering page behavior and exposing credentials or session data. The flaw requires valid authentication and can be leveraged by insiders or attackers with stolen credentials.

Affected Systems

Versions of IBM API Connect from 10.0.8.0 through 10.0.8.12 and from 12.1.0.0 through 12.1.1.2 are vulnerable. Administrators should validate the installed product version and plan for an upgrade to the latest release.

Risk and Exploitability

The CVSS score is 6.4, indicating moderate severity. EPSS information is not available and the flaw is not present in the CISA KEV list. Exploitation depends on a legitimate authenticated session, so the threat is primarily to environments with privileged user access or compromised credentials. Nonetheless, the potential for credential leakage and malicious UI manipulation justifies prompt action.
