CVE-2026-68497Public exploitNetwork attack vectorHinoki check available

CPU denial of service via unbounded XML-number parsing

Published Sep 11, 2026 · Updated Sep 11, 2026

CPU exhaustion in FasterXML jackson-databind allows remote attackers to stall JSON processing via crafted XML datatype strings. CoreXMLDeserializers.Std._deserialize passes unchecked strings to DatatypeFactory for Duration or XMLGregorianCalendar, bypassing JSON-number length limits and triggering quadratic numeric parsing. Applications must bind untrusted input to these types; default mappers suffice, and concurrent requests can saturate worker threads without disclosing or modifying data.
