AI analysis
SAP Integration Suite does not sufficiently validate XML documents accepted from untrusted sources in certain internal components, permitting XML external entity (XXE) injection (CWE-611). An attacker with low-privilege (authenticated) access can submit specially crafted XML payloads containing malicious external entity declarations over the network, with no user interaction required. Successful exploitation lets the attacker read sensitive files from the server, with the contents exposed through monitoring or logging output, and can also cause resource exhaustion; confidentiality impact is high, availability impact is low, and there is no integrity impact (CVSS 3.1 score 8.5, scope changed). Any organization running SAP Integration Suite, a cloud-delivered platform whose tenants consume SAP-managed components, is affected until the September 2026 SAP security updates are applied. No exploitation has been observed so far: there is no public proof-of-concept, the flaw is not in CISA KEV, and EPSS assigns only a 0.2% probability of exploitation within the next 30 days.
What to do: Apply the SAP Integration Suite fixes released in the September 2026 SAP Security Patch Day, locating the corresponding SAP security note via CVE-2026-76958 for the exact component and version details (not disclosed in this data). Because file contents may be exposed through monitoring or logging output, review relevant logs for signs of XXE probing or leaked sensitive data and treat affected log stores as potentially containing sensitive information. Additionally, restrict low-privilege access to XML-accepting endpoints and disable or limit external entity resolution where configuration options allow.

largelikely tens of thousands of cloud tenants/subscriptions (order-of-magnitude estimate; no counts in source data) — No install or tenant counts are provided in the source data, so this is inferred from SAP Integration Suite's role as SAP's primary cloud integration (iPaaS) platform with a broad enterprise tenant base, where the vulnerable components run…

Description
SAP Integration Suite does not sufficiently validate XML documents accepted from untrusted sources in certain internal components. An attacker with low privileges could submit specially crafted XML payloads containing malicious external entity declarations. Successful exploitation could allow the attacker to read sensitive file contents from the server and expose them through monitoring or logging output, resulting in a high impact on confidentiality. It could also lead to resource exhaustion, causing a low impact on availability. There is no impact on integrity.
