CVE-2026-84368 joi: Prototype pollution via a `__proto__` language key in custom messages

joi is a schema description language and data validator for JavaScript. From 16.0.0 until 17.13.6 and 18.2.5, the @hapi/joi package through 17.1.1 and the successor joi package contain prototype pollution in lib/messages.js, where exports.compile and exports.merge reuse inherited objects for...

CVE-2026-84368

joi (and its predecessor @hapi/joi ), a JavaScript schema validator, is affected by a prototype pollution vulnerability in lib/messages.js. The functions exports.compile() and exports.merge() reuse inherited objects for attacker-controlled language keys (e.g., __proto__ or constructor), which can...

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...

ca.uhn.hapi.fhir/org.hl7.fhir.utilities: HAPI FHIR XsltUtilities: XML External Entity injection allows local file disclosure and SSRF

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-2026-62293

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, the hidden scan command concatenates attacker-controlled Implementation Guide titles, profile titles, and source references into scan.html without escaping in Scanner.java. As...

CVE-2026-62296

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, XhtmlParser.java imposes no maximum element nesting depth, so a deeply nested text.div narrative triggers unbounded recursion between parseElementInner and parseElement, raisi...

CVE-2026-62295

HAPI FHIR (Java) prior to 6.9.11 has a denial-of-service risk: the JSON parser in org.hl7.fhir.utilities.json.parser.JsonParser enforces no maximum nesting depth, so deeply nested, valid FHIR JSON can trigger unbounded readArray/readObject recursion and cause a StackOverflowError before validatio...

CVE-2026-62295 HAPI FHIR: JSON utility parser unbounded recursion causes StackOverflow denial of service

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, the JSON utility parser in org.hl7.fhir.utilities.json.parser.JsonParser enforces no maximum nesting depth for arrays or objects. As a result, a small but deeply nested,...
