EPSS · scored 2026-10-27

jackson-core contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. From version 3.0.0 to before version 3.1.0, the UTF8DataInputJsonParser, which is used when parsing from a java.io.DataInput source, bypasses the maxNestingDepth constraint (default: 500) defined in StreamReadConstraints. A similar issue was found in ReaderBasedJsonParser. This allows a user to supply a JSON document with excessive nesting, which can cause a StackOverflowError when the structure is processed, leading to a Denial of Service (DoS). This issue has been patched in version 3.1.0.

  • GHSA-6v53-7c9g-w56rjackson-core has Nesting Depth Constraint Bypass in `UTF8DataInputJsonParser` potentially allowing Resource Exhaustion2026-03-04ghsa · osvUS

    ### Summary The `UTF8DataInputJsonParser`, which is used when parsing from a `java.io.DataInput` source, bypasses the `maxNestingDepth` constraint (default: 500) defined in `StreamReadConstraints`. A similar issue was found in `ReaderBasedJsonParser`. This allows a user to supply a JSON document with excessive nesting, which can cause a `StackOverflowError` when the structure is processed, leading to a Denial of Service (DoS). The related fix for com.fasterxml.jackson.core:jackson-core, CVE-2025-52999, was not fully applied to tools.jackson.core:jackson-core until the 3.1.0 release. It is recommended that 3.0.x users upgrade. ### Patches jackson-core contains a configurable limit for how deep Jackson will traverse in an input document. This check was missing in a few places in tools.jackson.core:jackson-core. The change is in https://github.com/FasterXML/jackson-core/pull/1554. jackson-core will throw a StreamConstraintsException if the limit is reached. jackson-databind also benefits from this change because it uses jackson-core to parse JSON inputs. ### Workarounds Users should avoid parsing input files from untrusted sources. ### Resources [GHSA-6v53-7c9g-w56r](https://github.com/FasterXML/jackson-core/security/advisories/GHSA-6v53-7c9g-w56r) https://nvd.nist.gov/vuln/detail/CVE-2025-52999 https://github.com/FasterXML/jackson-core/pull/1554
