CVE-2026-18401

The non-blocking asynchronous JSON parser in jackson-core does not enforce the maxNumberLength constraint defined in StreamReadConstraints default: 1000 characters. An attacker able to submit JSON to an application that uses the async parser API can supply a number token of arbitrary length,...

PYSEC-2026-3562 `datamodel-code-generator` vulnerable to code execution on import via `x-python-type` JSON-Schema extension in datamodel-code-generator

Summary datamodel-code-generator honours a custom x-python-type JSON-Schema extension that lets a schema author override the generated Python type for a field. The value is forwarded verbatim into the generated Python source as the field annotation, with a single sanitisation pass that is trivial...

datamodel-code-generator vulnerable to SSRF via JSON-Schema `$ref` to HTTP URL (silent by default)

SummaryJSON-Schema $ref values pointing at HTTP or HTTPS URLs are silently dereferenced by datamodel-code-generator with no IP/host validation, no scheme allow-list, and redirects followed unconditionally. The --allow-remote-refs gate added in 0.56.0 defaults to None, which only emits a deprecati...

datamodel-code-generator vulnerable to arbitrary local file read via JSON-Schema `$ref` (`file://` and `../` traversal), bypassing `--no-allow-remote-refs`

Summarydatamodel-code-generator resolves JSON-Schema $ref targets that point at the local filesystem without restricting them to the input/base directory and without honoring the remote-reference security control. In the default configuration, an attacker who controls an input schema a "paste you...

`datamodel-code-generator` vulnerable to code injection in via attacker-controlled `default_factory` schema field

Summarydatamodel-code-generator is vulnerable to code injection when generating Python models from an attacker-controlled JSON Schema, OpenAPI, YAML, JSON, Avro, Protobuf, or XSD schema. When a property carries a "defaultfactory" key, its value is interpolated verbatim — as a raw Python expressio...

github.com/go-jose/go-jose/v3: github.com/go-jose/go-jose/v4: Go JOSE: Denial of Service via crafted JSON Web Encryption (JWE) object

A flaw was found in Go JOSE, a library for handling JSON Web Encryption JWE objects. A remote attacker could exploit this vulnerability by providing a specially crafted JWE object. When decrypting such an object, if a key wrapping algorithm is specified but the encrypted key field is empty, the...

SpEL Expression Injection

Spring Data REST is vulnerable to SpEL expression injection through map-typed properties when processing JSON Patch requests. The vulnerability is due to the JSON Pointer path segment used as the map key being embedded directly into a SpEL expression without sanitization or validation, where...
