Red Hat Build Of Debezium 3

Unauthenticated remote file read in RESTEasy's SourceProvider component allows network attackers to exfiltrate arbitrary server-side files by exploiting an XML External Entity (XXE) flaw. The vulnerability exists because SourceProvider.writeTo() instantiates a SAXParser without disabling external entity resolution, so any endpoint that accepts application/xml and returns a Source or StreamSource type will parse attacker-controlled DOCTYPE declarations and leak file contents in the HTTP response. CVSS rates this 7.5 (High) with full confidentiality impact; no public exploit code or CISA KEV listing is identified at time of analysis, but the low-complexity unauthenticated network vector makes this a credible threat wherever RESTEasy-backed XML endpoints are exposed.
WildFly Elytron's password hashing and verification subsystem silently normalizes Unicode input via NFKC before hashing, collapsing fullwidth characters (e.g., U+FF21 'Ａ') to their ASCII equivalents (e.g., 'A'). This allows an unauthenticated remote attacker to authenticate against accounts whose owners believed their passwords contained unique non-ASCII characters by submitting a standard ASCII-only dictionary - the normalization makes the stored hash indistinguishable from its ASCII equivalent. Affected deployments span Red Hat JBoss EAP 7 and 8, Red Hat Build of Keycloak, Red Hat Data Grid 8, and several other Red Hat middleware products that share the Elytron security layer. No public exploit code or CISA KEV listing has been identified at time of analysis.
