Vulnerability Title
Apicurio/apicurio-registry: apicurio-registry: xml entity-expansion denial of service via internal dtd subset
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in Apicurio Registry. The DocumentBuilderAccessor correctly blocks external DTD and schema access but does not disable DOCTYPE declarations or enable FEATURE_SECURE_PROCESSING. An attacker with artifact-write permission can upload XML documents with internal entity-expansion payloads (billion-laughs variant) that cause CPU and heap exhaustion, partially mitigated by the JAXP default 64,000 entity-expansion limit.
