Security Bulletin


Summary

IBM App Connect Enterprise Certified Container images may be vulnerable to Denial of Service attacks due to regular expression DoS vulnerabilities in the Node module npm. The npm module is not used at runtime by IBM App Connect Enterprise itself, but anyone using the certified containers as a base for their images may then have a version of npm that contains CVE-2021-23362 and CVE-2021-27290
