CVE Severity Published▾ Status Exploitation Description
CVE-2026-54512 High 2026-06-23 No exploit published Proof of concept only jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4, jackson-databind's PolymorphicTypeValidator (PTV) is the primary safety mechanism guarding polymorphic deserialization. When polymorphic typing is enabled and a type identifier contains generic parameters (i.e. the type ID string contains <), DatabindContext._resolveAndValidateGeneric() validates only the raw container class name (the substring before <) against the configured PTV. If the container type is approved, the method parses the full canonical type string via TypeFactory.constructFromCanonical() and returns the fully parameterized type without ever validating the nested type arguments against the PTV. The nested type arguments are then resolved, instantiated, and populated as beans during deserialization. An attacker who controls the type ID can therefore place a denied class as a generic type parameter of an allowed container — for example java.util.ArrayList<com.evil.Gadget> when only java.util.ArrayList is allow-listed. The container passes the PTV check; com.evil.Gadget is loaded via Class.forName(name, true, loader), instantiated, and its properties are set from attacker-controlled JSON. This completely bypasses an explicitly configured PTV allow-list. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4.
CVE-2022-40152 High 2022-09-16 No exploit published Proof of concept only Those using Woodstox to parse XML data may be vulnerable to Denial of Service attacks (DOS) if DTD support is enabled. If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. This effect may support a denial of service attack.
CVE-2020-36179 High 2021-01-07 Mitigation candidate Proof of concept only FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to oadd.org.apache.commons.dbcp.cpdsadapter.DriverAdapterCPDS.
CVE-2020-36188 High 2021-01-06 Protected by Waratek Proof of concept only FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to com.newrelic.agent.deps.ch.qos.logback.core.db.JNDIConnectionSource.
CVE-2020-36184 High 2021-01-06 Mitigation candidate Proof of concept only FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to org.apache.tomcat.dbcp.dbcp2.datasources.PerUserPoolDataSource.
CVE-2020-35728 High 2020-12-27 Mitigation candidate Proof of concept only FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to com.oracle.wls.shaded.org.apache.xalan.lib.sql.JNDIConnectionPool (aka embedded Xalan in org.glassfish.web/javax.servlet.jsp.jstl).
CVE-2020-10673 High 2020-03-18 Mitigation candidate Proof of concept only FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to com.caucho.config.types.ResourceRef (aka caucho-quercus).
CVE-2020-8840 Critical 2020-02-10 Mitigation candidate Proof of concept only FasterXML jackson-databind 2.0.0 through 2.9.10.2 lacks certain xbean-reflect/JNDI blocking, as demonstrated by org.apache.xbean.propertyeditor.JndiConverter.
CVE-2019-14540 Critical 2019-09-15 Protected by Waratek Proof of concept only A Polymorphic Typing issue was discovered in FasterXML jackson-databind before 2.9.10. It is related to com.zaxxer.hikari.HikariConfig.
CVE-2019-14439 High 2019-07-30 Protected by Waratek Proof of concept only A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9.2. This occurs when Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the logback jar in the classpath.
CVE-2019-12384 Medium 2019-06-24 Protected by Waratek Proof of concept only FasterXML jackson-databind 2.x before 2.9.9.1 might allow attackers to have a variety of impacts by leveraging failure to block the logback-core class from polymorphic deserialization. Depending on the classpath content, remote code execution may be possible.
CVE-2019-12814 Medium 2019-06-19 Protected by Waratek Proof of concept only A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x through 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has JDOM 1.x or 2.x jar in the classpath, an attacker can send a specifically crafted JSON message that allows them to read arbitrary local files on the server.
CVE-2017-7525 Critical 2018-02-06 Protected by Waratek Proof of concept only A deserialization flaw was discovered in the jackson-databind, versions before 2.6.7.1, 2.7.9.1 and 2.8.9, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper.
