Title
XML External Entity injection in Szafir and Szafir Weryfikująca
Summary
Szafir and Szafir Weryfikująca are vulnerable to XML External Entity (XXE) injection. When a user signs or verify a crafted XML file containing a `DOCTYPE` with an external DTD reference, the parser processes external entities, allowing an attacker to read arbitrary files from the victim's filesystem. This issue was fixed in Szafir version 2.0 build 708. Szafir Weryfikująca is no longer supported (End of Life) and has not been fixed.

CVE-2026-92877 (GCVE-0-2026-92877)

Vulnerability from cvelistv5 – Published: 2026-10-12 14:19 – Updated: 2026-10-16 17:05
VLAI
Summary
The JAXB factory methods historically relied solely on `FEATURE_SECURE_PROCESSING` to prevent XML External Entity (XXE) resolution. On JAXP implementations where that feature alone does not block external entity resolution, an attacker who can get untrusted XML unmarshalled through JAXB can read local files via out-of-band XXE.

CVE-2026-92198 (GCVE-0-2026-92198)

Title
Quest Foglight for Databases getSource XML External Entity Processing Information Disclosure Vulnerability
Summary
Quest Foglight for Databases getSource XML External Entity Processing Information Disclosure Vulnerability. This vulnerability allows remote attackers to initiate arbitrary server-side requests on affected installations of Quest Foglight for Databases. Authentication is not required to exploit this vulnerability. The specific flaw exists within the getSource method. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of the application. Was ZDI-CAN-29934.

CVE-2026-91858 (GCVE-0-2026-91858)

Title
Apache Camel: Camel-FOP Resolves External DTDs and Entities From Untrusted XSL-FO Input When a Third-Party JAXP TransformerFactory Is Present
Summary
FopProducer transforms the incoming XSL-FO message body by creating a javax.xml.transform.TransformerFactory through TransformerFactory.newInstance() and enabling only FEATURE_SECURE_PROCESSING before running an identity transform over the body. On the JDK's built-in transformer, that feature alone already empties the accessExternalDTD and accessExternalStylesheet limits, so an external DTD or entity is refused. When a third-party JAXP TransformerFactory such as Saxon-HE is on the classpath, for example because the application also uses camel-xslt-saxon or camel-saxon, TransformerFactory.newInstance() returns that implementation instead, and FEATURE_SECURE_PROCESSING on its own does not restrict external resource access on it. A DOCTYPE with an external subset, or an external general entity, declared in the XSL-FO document is then resolved and expanded while the body is transformed. An external sender whose XSL-FO reaches a fop producer could therefore read files readable by the Camel process and cause the process to issue requests to hosts the document names. camel-fop does not bring such a factory itself, and excludes Xalan, so a default deployment using the JDK transformer is not affected; the issue is reachable only where another component has placed an alternative JAXP TransformerFactory on the classpath. Releases on the 4.14.x line and earlier reached end of life before this issue was resolved and do not receive a fix.

Title
Flowable flowable-engine through 8.0.0 XXE via ProcessDiagramLayoutFactory
Summary
Flowable flowable-engine through 8.0.0 contains an XML external entity injection vulnerability in ProcessDiagramLayoutFactory.parseXml() that fails to disable external entity resolution when parsing deployed BPMN resources. Attackers with process deployment privileges can embed DOCTYPE declarations with external entities in BPMN files to read arbitrary local files or trigger requests to internal network endpoints when diagram layout is computed.

Title
Apache Camel: Camel-Saxon XML External Entity Processing - XQueryBuilder Parsed a Message Body That Was Already a javax.xml.transform.Source With Saxon's Default Parser Settings, so an External Entity Declared in That Body Was Resolved
Summary
Improper Restriction of XML External Entity Reference vulnerability in Apache Camel Saxon component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.2. XQueryBuilder in camel-saxon, which evaluates expressions for the xquery language and the xquery component, built its default Saxon Configuration with parse options that set only a whitespace stripping rule, leaving the XML parser at its defaults, under which a DOCTYPE declaration is accepted and external entities are resolved. A message body of type String or byte[], or any body read as an InputStream, is first turned into a javax.xml.transform.Source by Camel's own XML type converters, which configure the parser against external entities, so those bodies were not affected. A body that was already a Source, however, was handed to Saxon unchanged, and when that Source still had to be parsed, as a stream-based Source does, Saxon parsed it with that Configuration, bypassing the protection applied to the other body types. Such a body arises, for example, after a route converts the message with convertBodyTo(Source.class), or when a component or processor earlier in the route sets the body to a stream-based Source. A DOCTYPE with an external subset, or an external entity, declared in that body was therefore resolved and expanded into the document the expression was evaluated against. An external sender whose XML reaches an XQuery expression or an xquery endpoint in that form could read files readable by the Camel process and cause the process to issue requests to hosts the document names. No non-default option is required, since the default Configuration is used whenever the route does not supply one of its own. Users are recommended to upgrade to version 4.23.0, which fixes the issue. If users are on the 4.22.x releases stream, then they are suggested to upgrade to 4.22.2. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.5. The 4.14.x releases stream and earlier, as well as the 4.15.x to 4.17.x and 4.19.x to 4.21.x release lines, reached end of life before this issue was resolved and will not receive a fix, so deployments on them must move to a supported release. For deployments that cannot upgrade immediately, do not evaluate XQuery over a message body that is already a javax.xml.transform.Source when that body carries XML from an untrusted sender, or set the configuration option of the xquery endpoint or language to a Saxon Configuration whose parse options refuse a DOCTYPE declaration and disable external entities and external DTD loading, which is what the fixed releases now apply by default.

A Configuration supplied through the configuration option of the xquery endpoint or language is used as is and is not modified.

CVE-2026-89260 (GCVE-0-2026-89260)

Title
MoguBlog through 6.2 XML External Entity Injection in the Unauthenticated WeChat Callback Endpoint
Summary
MoguBlog through 6.2 contains an XML external entity injection vulnerability in the WeChat callback handler at POST /wechat/wechatCheck. The WechatRestApi.index() method passes the raw request body to SignUtil.xmlToMap(), which uses an unhardened dom4j SAXReader without DTD or external-entity restrictions. Unauthenticated remote attackers can submit DOCTYPE declarations with external parameter entities to read arbitrary local files or trigger outbound HTTP requests, with resolved entities reflected in error responses.

Mitigation
Implementation System Configuration

Many XML parsers and validators can be configured to disable external entity expansion.

CAPEC-221: Data Serialization External Entities Blowup

This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
