SCA: security update for com.fasterxml.jackson.core:jackson-databind, tools.jackson.core:jackson-databind (GHSA-q4xh-88c3-wmh7)

high Tenable Cloud Security Plugin ID 448452

Description

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

 - jackson-databind binds a JSON string to a javax.xml.datatype.Duration or
 javax.xml.datatype.XMLGregorianCalendar field by passing the raw string verbatim to
 DatatypeFactory.newDuration(value) or newXMLGregorianCalendar(value) in
 CoreXMLDeserializers.Std._deserialize. These deserializers are registered by default with no opt-in, so a
 plain ObjectMapper or JsonMapper with no polymorphic typing and no special configuration reaches this
 path. The XML Schema lexical grammar permits numeric components of arbitrary length, which the JDK
 materializes through the native BigInteger(String) and BigDecimal(String) constructors, both quadratic in
 digit count. Because the digits sit inside a JSON string token rather than a JSON number token, jackson-
 core's StreamReadConstraints.maxNumberLength guard never applies; jackson's own NumberDeserializers call
 validateIntegerLength or validateFPLength before parsing a stringified number, but the XML datatype
 deserializer omits that pre-check. An unauthenticated attacker can therefore submit a single request of a
 few megabytes, such as a Duration value consisting of the letter P followed by several million digits and
 the letter Y, and force tens of seconds to several minutes of single-threaded CPU work; a handful of
 concurrent requests can saturate a server's worker threads. This affects
 com.fasterxml.jackson.core:jackson-databind from 2.0.0 before 2.18.10, from 2.19.0 before 2.21.6, and from
 2.22.0 before 2.22.2, and tools.jackson.core:jackson-databind from 3.0.0 before 3.1.6 and from 3.2.0
 before 3.2.2. Users should upgrade to 2.18.10, 2.21.6, 2.22.2, 3.1.6, or 3.2.2. (CVE-2026-68497)

Solution

Update the com.fasterxml.jackson.core:jackson-databind library and its related packages to version 2.18.10 or later.
