🦉 Allocation of Resources Without Limits or Throttling

[bwappsec]

This is a major upgrade for the Jackson suite, jumping from version 2.9.x to 2.18.6. This update spans numerous releases and introduces significant breaking changes, new features, and a higher Java baseline requirement.

Key Breaking Changes:

• Java Version Requirement: The minimum Java version has been increased. jackson-databind requires Java 8 since version 2.13, and jackson-core requires Java 8 since version 2.14. Your project must be on Java 8 or later. [2, 5, 13]

• Safe Default Typing (Polymorphic Deserialization): To address multiple security vulnerabilities (CVEs), version 2.10 introduced a new "Safe Default Typing" mechanism. The previous methods for enabling polymorphic typing are now considered unsafe and have been replaced. If your application uses this feature, you must migrate to the new activateDefaultTyping() methods to ensure security and functionality. [4]

• Behavioral Changes:

  • Stricter Deserialization: Later versions have introduced stricter parsing rules. For example, in 2.17, strings with leading zeros (e.g., "07") are no longer automatically coerced into numbers. [1]
  • @JsonIgnore Precedence: As of version 2.14, @JsonIgnore is now consistently given priority over other annotations like @JsonProperty, which may cause fields to be unexpectedly excluded from serialization/deserialization. [13]
  • Null Handling: In version 2.13, Jackson stopped coercing a JSON null value into the literal string "null" in certain contexts, which may affect applications that relied on this behavior. [2]

• Dependency Changes: The jackson-dataformat-xml module no longer has a direct dependency on jackson-module-jaxb-annotations as of version 2.13. [2, 6]

Recommendation:

Due to the number of breaking changes and the long span of versions, this upgrade requires careful testing and likely code modifications. Pay special attention to:

1. Ensuring your environment uses Java 8 or newer.
2. Updating any code that uses polymorphic type handling to the new "Safe Default Typing" APIs.
3. Thoroughly testing your application's JSON/XML serialization and deserialization logic to catch any issues arising from the stricter parsing and behavioral changes.
