expat before version 2.4.0 does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE.

CVE-2026-918765.5 MÉD—
———Dell OpenManage Ansible Modules, versions 2.0.4 through 10.0.3, contains an Improper Restriction of XML External Entity Reference vulnerability in the XML parsing component. A low privileged attacker with local access could potentially exploit this vulnerability, leading to information exposure.10hCVE-2026-1051537.7 ALT—
———Improper Restriction of XML External Entity Reference in Apache Roller 4.0 through 6.1.6 allows an authenticated user with no weblog permissions to read files readable by the Roller process and cause the server to issue outbound HTTP requests to attacker-chosen destinations, by submitting a crafted Atom entry to the AtomPub endpoint. The entry body is parsed with a parser configuration that permits external parameter entities and external DTD subsets, and the parse happens before any per-weblog authorization check and before any check of whether the AtomPub feature is enabled, so the endpoint is reachable by any authenticated account on a default installation. Users are recommended to upgrade to Apache Roller 6.1.7 or later, which parses AtomPub entries with a hardened XML configuration and rejects AtomPub requests while the feature is disabled.16hCVE-2026-90993——
——0XXE vulnerability in Apache XML Graphics Batik.
This issue affects Apache XML Graphics Batik: through 1.19.
Users are recommended to upgrade to version 1.20, which fixes the issue.10hCVE-2026-125883—59.6%
