Kerentanan Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion') pada redhat build of apicurio registry. Skor CVSS 3.1 6.5 (Medium) menurut redhat.com.

Deskripsi (NVD)

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.
