Loading vulnerability…
CVE-2019-14439 is an unsafe polymorphic deserialization vulnerability in FasterXML jackson-databind 2.x releases prior to 2.9.9.2. When Default Typing is enabled globally or on a property, an externally exposed JSON endpoint can deserialize attacker-controlled type metadata. If Logback is present on the application classpath, gadget classes involving Logback and JNDI can be invoked during deserialization, enabling unsafe object construction and behavior.

A Jackson Databind polymorphic-typing vulnerability related to Logback and JNDI.
A jackson-databind polymorphic typing issue related to logback and JNDI.
A polymorphic deserialization issue in FasterXML jackson-databind versions before 2.9.9.2. Exploitation requires deserialization of untrusted input with Default Typing enabled, use of @JsonTypeInfo with id.CLASS or id.MINIMAL_CLASS, and the logback JAR on the classpath.
A moderate-severity (CVSS 7.5) unsafe polymorphic deserialization vulnerability in FasterXML jackson-databind. When an application deserializes attacker-controlled data and enables unsafe type handling, such as enableDefaultTyping() or @JsonTypeInfo with Id.CLASS or Id.MINIMAL_CLASS, attackers may instantiate malicious gadget objects and execute arbitrary code.
