CVE-2026-55471

A flaw was found in the HAPI FHIR XsltUtilities component. The saxonTransform functions within this utility do not adequately restrict external entity access when processing XML. This oversight allows an attacker, who can control or tamper with the XML data being transformed, to inject malicious...

CVE-2026-55470

A flaw was found in HAPI FHIR, a Java implementation of the HL7 FHIR standard. The fix for a previous vulnerability CVE-2026-45367 was incomplete in the DSTU2 module. Specifically, the FHIRPathEngine.matches function in org.hl7.fhir.dstu2 did not include protection against regular expression...

CVE-2026-49485 HAPI FHIR: ReDoS via FHIRPath matches()/replaceMatches() in FHIR Validator HTTP Endpoint

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.9 and 6.9.4.2, all implementations of FHIRPathEngine accept arbitrary FHIRPath expressions and evaluate them without input validation, and the FHIRPath functions matches,...

CVE-2026-49485

Summary: CVE-2026-49485 affects HAPI FHIR’s FHIRPathEngine (matches(), matchesFull(), replaceMatches()) where user-controlled regex patterns are compiled via Java’s regex engine, enabling ReDoS and CPU exhaustion. The issue exists in implementations prior to version 6.9.9 and 6.9.4.2. An attacker...

CVE-2026-45367

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.7, the FHIRPathEngine implementation passes user-controlled regular expressions from matches, matchesFull, and replaceMatches to Java regex operations without effective timeouts,...

CVE-2026-45367

CVE-2026-45367 affects HAPI FHIR DSTU2 module (org.hl7.fhir.dstu2) where FHIRPathEngine.matches() still calls String.matches() without a timeout, enabling potential ReDoS via user-supplied FHIRPath expressions. Other modules (DSTU2016MAY, DSTU3, R4, R4B, R5) have RegexTimeout protection and are f...
