Summary

SAPUI5 (and OpenUI5) packages use outdated 3rd party libraries with known security vulnerabilities. When markdown-it encounters special malformed input, it fails to terminate properly, resulting in an infinite loop. This Denial of Service via infinite loop causes high CPU usage and system unresponsiveness due to a blocked processing thread. This vulnerability has no impact on confidentiality or integrity but has a high impact on system availability.
