🦉 Allocation of Resources Without Limits or Throttling

[snyk-io]

This upgrade to Jackson 2.18.6 introduces significant internal changes and drops support for older Kotlin versions, warranting a medium risk assessment.

While a minor version update, developers should be aware of the following:

• Property Introspection Rewrite: jackson-databind underwent a major internal rewrite of its POJO property introspection logic. While this fixed many long-standing bugs, the release notes for subsequent patches explicitly mention and fix behavioral changes in deserialization between versions 2.17 and 2.18, particularly for Java Records, @JsonCreator, and Throwable subclasses.
• Kotlin Version Support: Support for Kotlin 1.7.x has been dropped. Projects using Jackson with Kotlin must now use version 1.8, 1.9, or 2.0.
• Behavioral Change in UTF-8 Handling: jackson-core now correctly encodes supplementary Unicode characters using a 4-byte sequence instead of a surrogate pair. This is a bug fix but could impact systems that relied on the previous incorrect behavior.

Recommendation: Due to the internal rewrite and documented behavioral changes, it is critical to perform thorough regression testing on serialization and deserialization logic, especially for complex POJOs, Java Records, and classes using creator methods (@JsonCreator). If using Kotlin, verify your environment meets the new version requirements.
