assertj: AssertJ: Information disclosure and denial of service via XML External Entity (XXE)

A flaw was found in AssertJ. An XML External Entity XXE vulnerability exists in the XmlStringPrettyFormatter component, which is used by the isXmlEqualToCharSequence assertion. If an application processes untrusted XML input using these methods, a remote attacker could exploit this flaw to read...

cxf: org.apache.cxf/cxf-core: Apache CXF: Information disclosure via out-of-band external entity resolution due to missing JAXP hardening

A flaw was found in Apache CXF. The EndpointReferenceUtils and W3CMultiSchemaFactory classes within Apache CXF construct a SAXParserFactory without proper security configurations. This oversight enables out-of-band OOB external entity resolution, a type of XML External Entity XXE vulnerability. A...

PYSEC-2026-1765 Peppol-py is vulnerable to XXE attacks due to Saxon configuration

Peppol-py before 1.1.1 allows XXE attacks because of the Saxon configuration. When validating XML-based invoices, the XML parser could read files from the filesystem and expose their content to a remote host...

PYSEC-2026-1520 LangChain Text Splitters is vulnerable to XML External Entity (XXE) attacks due to unsafe XSLT parsing

The HTMLSectionSplitter class in langchain-text-splitters is vulnerable to XML External Entity XXE attacks due to unsafe XSLT parsing. This vulnerability arises because the class allows the use of arbitrary XSLT stylesheets, which are parsed using lxml.etree.parse and lxml.etree.XSLT without any...

PYSEC-2026-1515 Langchain Community Vulnerable to XML External Entity (XXE) Attacks

The langchain-ai/langchain project, specifically the EverNoteLoader component, is vulnerable to XML External Entity XXE attacks due to insecure XML parsing. The vulnerability arises from the use of etree.iterparse without disabling external entity references, which can lead to sensitive informati...
