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...

Apicurio/apicurio-registry: apicurio-registry: XML entity-expansion denial of service via internal DTD subset

A flaw was found in Apicurio Registry. The DocumentBuilderAccessor correctly blocks external DTD and schema access but does not disable DOCTYPE declarations or enable FEATURESECUREPROCESSING. An attacker with artifact-write permission can upload XML documents with internal entity-expansion payloa...
