Related CVEs

  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 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
  3. 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. This may result in acceptance of tampered identity information, unauthorized access to sensitive user data and potential disruption of normal system usage.•CVE-2026-23687
  4. 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-2026-23689
  5. Due to improper memory management in SAP NetWeaver and ABAP Platform (Application Server ABAP), an authenticated attacker could exploit logical errors in memory management by supplying specially crafted input containing unique characters, which are improperly converted. This may result in memory corruption and the potential leakage of memory content. Successful exploitation of this vulnerability would have a low impact on the confidentiality of the application, with no effect on its integrity or availability.•CVE-2026-24320
