CVE-2020-36518

CVE-2020-36518 affects jackson-databind prior to 2.13.0, enabling a Java StackOverflow and DoS via excessive nesting depth. In affected advisories, remediation is to upgrade jackson-databind to 2.13.0+ (examples show 2.13.x or newer such as 2.13.4.2 in Crowd/CWD references). Practical impact is d...

CVE-2022-42003

The CVE-2022-42003 issue affects FasterXML jackson-databind, where enabling UNWRAP_SINGLE_VALUE_ARRAYS allows resource exhaustion due to a missing check in primitive value deserializers to prevent deep wrapper array nesting. Affected versions are before 2.13.4.1 and 2.12.17.1; remediation per sou...

CVE-2020-25649

The CVE-2020-25649 entry concerns a flaw in FasterXML Jackson Databind where entity expansion was not properly secured, enabling XML External Entity (XXE) attacks. This is a data-integrity risk. Connected advisories consistently associate the issue with Jackson Databind and XXE, and several sourc...

CVE-2022-42004

The CVE affects FasterXML jackson-databind prior to 2.13.4, where resource exhaustion can occur due to a missing check in BeanDeserializer._deserializeFromArray that prevents deeply nested arrays. An application is vulnerable only with certain customized deserialization paths. Concrete details ac...

CVE-2021-46877

CVE-2021-46877 is an IBM-supported entry describing a Denial of Service in jackson-databind caused by JsonNode JDK serialization in certain Jackson 2.x releases. Affected are jackson-databind 2.10.x through 2.12.x before 2.12.6 and 2.13.x before 2.13.1. The impact is a 2 GB transient heap usage p...

CVE-2018-12023

The CVE-2018-12023 issue affects FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (globally or per-property) and the Oracle JDBC jar is in the classpath with an LDAP service accessible to an attacker, the service could be coerced into executing a ma...

CVE-2019-12086

CVE-2019-12086 involves a polymorphic typing issue in FasterXML jackson-databind 2.x prior to 2.9.9. When Default Typing is enabled for an externally exposed JSON endpoint and a victim service has mysql-connector-java (8.0.14 or earlier) on the classpath, an attacker can send a crafted JSON to re...

CVE-2019-14439

CVE-2019-14439 describes a polymorphic typing deserialization issue in FasterXML jackson-databind 2.x prior to 2.9.9.2. When Default Typing is enabled (globally or for a property) and logback is in the classpath, an externally exposed JSON endpoint may be vulnerable to unsafe deserialization. Aff...

CVE-2018-12022

CVE-2018-12022 affects FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (globally or for a property) and the service classpath contains the Jodd‑db jar (for Jodd DB access) with an LDAP service available, an attacker can trigger remote code executio...

CVE-2026-50193

jackson-databind contains a DoS in JSON tree handling: if a service reads deeply nested JSON (1000s of levels) via ObjectMapper.readTree() and then writes that JsonNode with toString(), it can consume significant resources. Affected are 2.13.0–2.14.0; fixed in 2.14.0. Mitigation: upgrade to 2.14....
