Summary
SAP BusinessObjects Business Intelligence Platform (Web Intelligence) does not properly restrict external entity resolution when processing OLAP connection requests, so an attacker with low-privilege login access over the network can read sensitive files on the server and reach internal systems that are otherwise not exposed. The flaw can also affect resources beyond the vulnerable component, with high impact to confidentiality and low impact to integrity and availability.

Read the original description
SAP BusinessObjects Business Intelligence Platform (Web Intelligence) does not properly restrict external entity resolution when processing OLAP connection requests. An authenticated attacker could exploit this vulnerability to access restricted resources, enabling them to read sensitive files on the server and reach internal systems that are not otherwise exposed, impacting resources beyond the vulnerable component, resulting in a high impact on confidentiality and a low impact on both integrity and availability.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-109798 (XML External Entity (XXE) Vulnerability in SAP BusinessObjects Business Intelligence Platform (Web Intelligence)), using the cve.now data below. Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only. What cve.now has for CVE-2026-109798 (entry last updated 2026-11-10): Affected: - SAP_SE SAP BusinessObjects Business Intelligence Platform (Web Intelligence): versions ENTERPRISE 430, 2025, 2027 Fixed versions: none listed yet. Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory. CISA KEV: CVE-2026-109798 is not listed as of cve.now's last read. This KEV status is for CVE-2026-109798 only. If you also check another CVE, look up its own KEV status; never assume it from this one. How to check: - Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory. Verify against the linked advisories before concluding, and cite the date you read each one: - https://me.sap.com/notes/3799117 - https://url.sap/sapsecuritypatchday Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing. Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
