CVE-2026-107377

datamodel-code-generator generates Python data models from schema definitions. From 0.59.0 until 0.81.0, an attacker-controlled Protobuf schema can supply absolute or parent-directory paths captured by WEAKIMPORTPATTERN and consumed by writemissingweakimports in...

datamodel-code-generator: Protobuf weak-import path traversal allows files to be written outside the temporary directory

Summary When processing an attacker-controlled Protobuf schema, vulnerable versions of datamodel-code-generator could write a generated weak-import stub outside the intended weakimports temporary directory. Absolute import paths and relative paths containing .. could escape this directory. An...

CVE-2026-107377

The datamodel-code-generator library (versions 0.59.0 through 0.81.0 ) is vulnerable to a path traversal attack when processing attacker-controlled Protobuf schemas. The root cause lies in the _write_missing_weak_imports function in src/datamodel_code_generator/parser/protobuf.py, which fails to ...

PYSEC-2026-3558 datamodel-code-generator vulnerable to arbitrary local file read via JSON-Schema `$ref` (`file://` and `../` traversal), bypassing `--no-allow-remote-refs`

Summary datamodel-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 yo...

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 code execution on import via `x-python-type` JSON-Schema extension in datamodel-code-generator

Summarydatamodel-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 ...

PYSEC-2026-3566 `datamodel-code-generator` vulnerable to code injection via unescaped carriage return in `--extra-template-data` `comment` field

Summary datamodel-code-generator is vulnerable to code injection when a developer passes an --extra-template-data file whose comment value contains a literal \r carriage return. The comment variable is rendered into a Python comment in six built-in templates with no line-terminator escaping...

PYSEC-2026-3560 datamodel-code-generator vulnerable to SSRF via JSON-Schema `$ref` to HTTP URL (silent by default)

PYSEC-2026-3563 datamodel-code-generator: Authorization / request headers leaked to cross-origin redirect target when fetching remote schemas

Summary When datamodel-code-generator fetches a remote schema and follows an HTTP redirect, it re-sends the original request headers, including any Authorization header, to the redirect target even when the redirect changes origin host/port/scheme. Credentials that an operator scoped to a trusted...
