SAP Process Integration (SOAP Adapter) allows a privileged user to send specially crafted requests containing deeply nested entity definitions, which under certain conditions could temporarily increase processor load and degrade system responsiveness. Successful exploitation results in low impact on availability with no impact on confidentiality and integrity.

CVE-2023-460355.9 MED—
———The svg_optimizer gem before 0.3.0 for Ruby performs entity expansion on untrusted documents.2hCVE-2026-161805.7 MED13.1%
——4IBM App Connect Enterprise 13.0.1.0 through 13.0.8.1, and 12.0.1.0 through 12.0.12.28 and IBM Integration Bus for z/OS 10.1.0.0 through 10.1.0.7 Toolkit could allow an authenticated user to cause a denial-of-service condition due to improper validation of XML entities.5dCVE-2026-786817.5 HIG21.9%
——7NLTK versions before 3.10.3 use xml.etree.ElementTree to parse XML in multiple modules, which honors entity declarations in document DTDs. Attackers can craft XML payloads with nested entity declarations that expand from hundreds of bytes to megabytes in memory, causing denial of service.13dCVE-2026-73569—30.6%
——9fast-xml-parser allows users to process XML from JS object without C/C++ based libraries or callbacks. From 5.9.3 until 5.10.1, src/xmlparser/OrderedObjParser.js processes multiple DOCTYPE declarations within a single XML document and passes each declaration's entities through addInputEntities(). addInputEntities() resets maxTotalExpansions and maxExpandedLength every time it is called, allowing additional DOCTYPE declarations to repeatedly reset the configured entity-expansion limits during one parse operation. A crafted XML document can then cause excessive CPU use, event-loop blocking, memory exhaustion, and process termination. This issue is fixed in version 5.10.1.32dCVE-2026-34158.7 HIG27.4%
——8The XML and schema validation functionalities within the SchemaValidator Mediator process XML input as part of validation flows. Under certain conditions, the XML parser allows the resolution of external entities when handling user-supplied XML content during validation operations. This behavior can occur when an attacker supplies crafted XML payloads to the relevant mediator flows with sufficient privileges.
Successful exploitation may allow a highly privileged actor to read files accessible within the server hosting the affected product. Additionally, it may be possible to trigger outbound requests to unintended internal or external locations, depending on the server environment and network configuration. Specially crafted XML payloads can also lead to excessive resource consumption during parsing, impacting the availability of the product.14dCVE-2026-148655.3 MED36.6%
——11In Progress® Telerik® UI for AJAX prior to v2026.2.708, the internal LayoutBuilder control processes client-state XML without disabling DTD processing, allowing unauthenticated denial of service via recursive XML entity expansion.39d
