Published:April 01, 2026
Updated:July 02, 2026
Jackson Core 3.x does not consistently enforce StreamReadConstraints.maxDocumentLength. Oversized JSON documents can be accepted without a StreamConstraintsException across blocking, async, and DataInput parser entry points, allowing configured document-length limits to be bypassed and weakening denial-of-service protections.
Affected Packages
tools.jackson.core:jackson-core (JAVA):
Affected version(s) >=3.0.0 <3.1.1
Fix Suggestion:
Update to version 3.1.1
