Found in base branch: main
Vulnerability Details
The non-blocking (async) JSON parser in jackson-core bypasses the maxNumberLength constraint (default: 1000 characters) defined in StreamReadConstraints. This allows an attacker to send JSON with arbitrarily long numbers through the async parser API, leading to excessive memory allocation and potential CPU exhaustion, resulting in a Denial of Service (DoS).
The standard synchronous parser correctly enforces this limit, but the async parser fails to do so, creating an inconsistent enforcement policy.

Found in base branch: main
Vulnerability Details
The jackson-core package is vulnerable to a Denial of Service (DoS) attack. The methods in the classes listed below fail to restrict input size when performing numeric type conversions. A remote attacker can exploit this vulnerability by causing the application to deserialize data containing certain numeric types with large values. Deserializing many of the aforementioned objects may cause the application to exhaust all available resources, resulting in a DoS condition.

- ❌ jackson-core-2.6.5.jar (Vulnerable Library)
Found in base branch: main
Vulnerability Details
jackson-core contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. In versions prior to 2.15.0, if a user parses an input file and it has deeply nested data, Jackson could end up throwing a StackoverflowError if the depth is particularly large. jackson-core 2.15.0 contains a configurable limit for how deep Jackson will traverse in an input document, defaulting to an allowable depth of 1000. 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. As a workaround, users should avoid parsing input files from untrusted sources.

In Jackson Core before version 2.8.6 if the REST endpoint consumes POST requests with JSON or XML data and data are invalid, the first unrecognized token is printed to server.log. If the first token is word of length 10MB, the whole word is printed. This is potentially dangerous and can be used to attack the server by filling the disk with logs.

Found in base branch: main
Vulnerability Details
Jackson-core contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. Starting in version 2.0.0 and prior to version 2.13.0, a flaw in jackson-core's "JsonLocation._appendSourceDesc" method allows up to 500 bytes of unintended memory content to be included in exception messages. When parsing JSON from a byte array with an offset and length, the exception message incorrectly reads from the beginning of the array instead of the logical payload start. This results in possible information disclosure in systems using pooled or reused buffers, like Netty or Vert.x. This issue was silently fixed in jackson-core version 2.13.0, released on September 30, 2021, via PR #652. All users should upgrade to version 2.13.0 or later. If upgrading is not immediately possible, applications can mitigate the issue by disabling exception message exposure to clients to avoid returning parsing exception messages in HTTP responses and/or disabling source inclusion in exceptions to prevent Jackson from embedding any source content in exception messages, avoiding leakage.
