Until a fix is available, consider restricting access to affected versions and carefully validating error message outputs to mitigate spoofing risks.
Description
IBM App Connect Enterprise versions 13.0.1.0 through 13.0.8.2 and 12.0.1.0 through 12.0.12.30 contain a vulnerability that allows remote attackers to perform content spoofing due to improper output encoding of error messages. This issue could lead to limited confidentiality and integrity impacts but does not affect availability.
