Summary

SAPUI5 and OpenUI5 packages use outdated third-party libraries with known vulnerabilities. When markdown-it encounters special malformed input, it fails to terminate properly, resulting in an infinite loop. This denial of service causes high CPU usage and system unresponsiveness due to a blocked processing thread.

Risk Assessment

An attacker can send specially crafted input, causing system overload and application unavailability. High CPU usage may impact the performance of the entire environment.

Recommendation

Update SAPUI5/OpenUI5 libraries to versions containing fixes for markdown-it. Also restrict access to input-processing functions and monitor resource usage.
