Descripción técnica

A flaw was found in RESTEasy's SourceProvider. This vulnerability allows an unauthenticated attacker to perform an unauthenticated remote file read. By sending a specially crafted XML body with a DOCTYPE declaration referencing external entities to an endpoint that accepts application/xml and returns Source or StreamSource, the server can be tricked into resolving the entity and including sensitive file contents in the HTTP response. This is due to the SourceProvider.writeTo() method creating a SAXParser without disabling external entity resolution, leading to an XML External Entity (XXE) vulnerability.

——0YaCy Search Server through 1.941 contains an XML external entity injection vulnerability in SVG, FreeMind, and OpenSearch parsers that fail to disable external entity resolution. Attackers can publish malicious documents with DOCTYPE declarations containing SYSTEM entities pointing to local files, causing the crawler to exfiltrate file contents into the searchable index.5h CVE-2026-558488.6 ALT

——8mapfish-print is a component of MapFish for printing templated cartographic maps. Prior to 3.28.30, 3.30.32, 3.31.24, 3.33.16, and 4.0.5, MapFish Print accepts an attacker-controlled GML layer url in requests to the /api/print3/print endpoint and fetches XML parsed by core/src/main/java/org/mapfish/print/map/geotools/GmlLayer.java without disabling external entities and external DTDs. A remote XML document and DTD can expand a local file entity, and the resulting content can be exposed through the GML parsing and error path. This allows unauthenticated attackers to read files such as operating-system account data, Kubernetes service-account tokens, and certificates. Replacing the file entity target with an internal HTTP endpoint also permits server-side request forgery. This issue is fixed in versions 3.28.30, 3.30.32, 3.31.24, 3.33.16, and 4.0.5.5h CVE-2026-765724.7 MED

——8A vulnerability was detected in pkp pkp-lib up to 3.3.0-22/3.4.0-10/3.5.0-4. The affected element is the function _transformPHP of the file classes/xslt/XSLTransformer.php. The manipulation results in xml external entity reference. The attack can be executed remotely. Upgrading to version 3.3.0-23, 3.4.0-11 and 3.5.0-5 is sufficient to fix this issue. The patch is identified as 78c699370ea43ae2784e1c4ace7c947d207f2b47. Upgrading the affected component is advised.11d CVE-2026-203207.5 ALT

——9A vulnerability in the Open Client Interface (OCI) XML Parser of Cisco BroadWorks could allow an unauthenticated, remote attacker to read sensitive configuration information on an affected system. This vulnerability exists because XML entries are improperly parsed due to external entity resolution being allowed by default. An attacker could exploit this vulnerability by sending a crafted XML message to the Open Client Interface – Provisioning (OCI-P) service. A successful exploit could allow the attacker to view sensitive files from the filesystem with the privileges of the Cisco BroadWorks user.11d CVE-2026-672686.5 MED
