Publication date: 2025-12-09

Last updated on: 2025-12-09

Assigner: SAP SE

Description
SAPUI5 (and OpenUI5) packages use outdated 3rd party libraries with known security vulnerabilities.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.

Executive Summary

This vulnerability exists in SAPUI5 and OpenUI5 packages that use outdated third-party libraries. Specifically, the markdown-it library fails to properly handle special malformed input, causing it to enter an infinite loop. This infinite loop leads to a Denial of Service (DoS) by causing high CPU usage and making the system unresponsive due to a blocked processing thread.

Impact Analysis

The vulnerability can cause a Denial of Service by making the affected system unresponsive and consuming high CPU resources. This impacts system availability but does not affect confidentiality or integrity.

Compliance Impact

This vulnerability primarily impacts system availability and does not affect confidentiality or integrity. Therefore, it has limited direct impact on compliance with standards focused on data protection like GDPR or HIPAA, which emphasize confidentiality and integrity. However, availability issues could indirectly affect compliance if system downtime impacts required service levels.
