Summary

SAP EPM Add-in for Microsoft Office, version - 1010 and SAP EPM Add-in for SAP Analysis Office, version - 2.8, allows an authenticated attacker with user privileges to parse malicious XML files which could result in XXE-based attacks in applications that accept attacker-controlled XML configuration files. This occurs as logging service does not disable XML external entities when parsing configuration files and a successful exploit would result in limited impact on integrity and availability of the application.

Exploit prediction

0.24% chance of exploitation in the next 30 days, higher than 14% of all scored CVEs (FIRST EPSS, 2026-11-08).
