  1. Due to an uncontrolled resource consumption (Denial of Service) vulnerability, an authenticated attacker with regular user privileges and network access can repeatedly invoke a remote-enabled function module with an excessively large loop-control parameter. This triggers prolonged loop execution that consumes excessive system resources, potentially rendering the system unavailable. Successful exploitation results in a denial-of-service condition that impacts availability, while confidentiality and integrity remain unaffected.•CVE-2026-27689
  2. SAP NetWeaver Enterprise Portal Administration is vulnerable if a privileged user uploads untrusted or malicious content that, upon deserialization, could result in a high impact on the confidentiality, integrity, and availability of the host system.•CVE-2026-27685
  3. SAP Solution Tools Plug-In (ST-PI) contains a function module that does not perform the necessary authorization checks for authenticated users, allowing sensitive information to be disclosed. This vulnerability has a high impact on confidentiality and does not affect integrity or availability.•CVE-2026-24322
  4. SAP NetWeaver Application Server ABAP and ABAP Platform allows an authenticated attacker with normal privileges to obtain a valid signed message and send modified signed XML documents to the verifier.
