SCA: security update for io.apicurio:apicurio-registry-schema-util-xml (GHSA-748j-wm96-4wh5)

medium Tenable Self-Hosted Container Security Plugin ID 478358

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-12993)

Solution

Update the io.apicurio:apicurio-registry-schema-util-xml library and its related packages to version 3.2.6 or later.
