What to do

GitHub lists first patched versions: io.apicurio:apicurio-registry-schema-util-common: 3.3.1; io.apicurio:apicurio-registry-schema-util-common: 3.2.6. Confirm the affected range and upgrade guidance in the exact advisory.

What happened

A flaw was found in Apicurio Registry. The ContentTypeUtil.isParsableXml() method creates a SAXParserFactory without enabling secure processing features or disabling external entity resolution. An attacker with artifact-write permission (or unauthenticated when the registry runs with default configuration) can upload a crafted XML document to trigger blind server-side request forgery (SSRF) via external DTD/entity fetch, or cause denial of service via entity expansion.

Affected package ranges reported by GitHub: io.apicurio:apicurio-registry-schema-util-common: >= 3.3.0, < 3.3.1 io.apicurio:apicurio-registry-schema-util-common: < 3.2.6

About this data

This record was ingested from a data source. Retrieved: Nov 4, 2026, 23:05 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
