CVE-2026-108385 (GCVE-0-2026-108385)

Vulnerability from nvd – Published: 2026-10-13 17:56 – Updated: 2026-10-13 18:15

Title

dataclasses-avroschema enum symbols can inject statements through generated member names

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, BaseGenerator.parse_enum and EnumRepresentation.render_symbols use each schema-controlled enum symbol as a generated enum member name after case conversion but without validating it as an identifier. When generator classes are used directly, newlines and punctuation can inject constrained statements into the generated enum class body, allowing namespace modification or preventing the module from loading. Version 0.70.6 fixes the vulnerability by validating every enum symbol as a name.

Severity

8.8 (High)

CVE-2026-108384 (GCVE-0-2026-108384)

Vulnerability from nvd – Published: 2026-10-13 17:53 – Updated: 2026-10-13 20:21

Title

dataclasses-avroschema allows code injection through fixed-type aliases supplied as a bare string

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, BaseGenerator.parse_fixed interpolates a fixed type's aliases value directly into a generated types.confixed annotation. A list is represented with quoted entries, but a bare string is emitted as an unquoted Python expression and evaluated when the generated module is imported, allowing arbitrary code execution from a crafted schema. Version 0.70.6 fixes the vulnerability by rejecting aliases values that are not lists.

Severity

8.8 (High)

CVE-2026-108383 (GCVE-0-2026-108383)

Vulnerability from nvd – Published: 2026-10-13 17:47 – Updated: 2026-10-14 15:58

Title

dataclasses-avroschema enum field defaults can inject statements into generated modules

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, FieldRepresentation.get_field_default renders a schema-controlled enum field default as an enum member reference after applying case conversion but without validating it as an identifier. Newlines, operators, and punctuation can escape the intended reference and inject constrained statements into the generated module, allowing namespace modification or preventing the module from loading. Version 0.70.6 fixes the vulnerability by validating enum defaults as names.

Severity

8.8 (High)

CVE-2026-108382 (GCVE-0-2026-108382)

Vulnerability from nvd – Published: 2026-10-13 17:44 – Updated: 2026-10-13 18:00

Title

dataclasses-avroschema allows code injection through generated enum-symbol string literals

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, EnumRepresentation.render_symbols concatenates each schema-controlled enum symbol between double quotes in a generated enum assignment. When generator classes are used directly, a quote can terminate the string literal and inject arbitrary Python code into the enum class body, which executes when the generated module is imported. Version 0.70.6 fixes the vulnerability by escaping enum symbol values before rendering them.

Severity

8.8 (High)

CVE-2026-108381 (GCVE-0-2026-108381)

Vulnerability from nvd – Published: 2026-10-13 17:43 – Updated: 2026-10-13 17:43

Title

dataclasses-avroschema pydantic-class metadata allows code injection in generated annotations

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.44.0 through 0.70.5, the Pydantic and AvroDantic model generators insert a schema field's pydantic-class value after pydantic. in a generated field annotation without safely restricting the expression. Because annotations are evaluated when the generated module is imported, a crafted value can execute arbitrary Python code. Version 0.70.6 fixes the vulnerability by restricting the value to a bare name or a call to a bare name with literal arguments.

Severity

8.8 (High)

CVE-2026-108380 (GCVE-0-2026-108380)

Vulnerability from nvd – Published: 2026-10-13 17:41 – Updated: 2026-10-13 18:17

Title

dataclasses-avroschema field documentation allows code injection in generated Pydantic descriptions

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.65.9 through 0.70.5, PydanticFieldRepresentation.add_field_properties inserts a schema field's doc value between the quotes of a generated pydantic.Field description argument without escaping it. A crafted quote can terminate the string and inject an expression evaluated during generated class definition, allowing arbitrary Python code execution for Pydantic and AvroDantic model generation. Version 0.70.6 fixes the vulnerability by escaping the documentation value before rendering it.

Severity

8.8 (High)

CVE-2026-108379 (GCVE-0-2026-108379)

Vulnerability from nvd – Published: 2026-10-13 17:40 – Updated: 2026-10-13 20:21

Title

dataclasses-avroschema fixed namespaces allow code injection in generated annotations

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, BaseGenerator.parse_fixed inserts a fixed type's namespace value between quotes inside a generated types.confixed annotation without escaping or validating it. A crafted quote can terminate the namespace string and alter the surrounding annotation expression, which Python evaluates when the generated class is defined, allowing arbitrary code execution. Version 0.70.6 fixes the vulnerability by requiring the namespace to be a dot-separated sequence of valid Avro names.

Severity

CVE-2026-108378 (GCVE-0-2026-108378)

Vulnerability from nvd – Published: 2026-10-13 17:34 – Updated: 2026-10-14 15:55

Title

dataclasses-avroschema record documentation can terminate generated class docstrings

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.40.0 through 0.70.5, ClassRepresentation.render_docstring copies a schema record's doc value into a generated triple-double-quoted class docstring without escaping quotes or backslashes. A crafted triple-quote sequence can close the docstring and inject statements into the generated class body, while a trailing backslash can escape the generated closing delimiter, allowing Python code execution during module import. Version 0.70.6 fixes the vulnerability by escaping quotes, backslashes, and unsafe control characters before rendering docstrings.

Severity

8.8 (High)

CVE-2026-108377 (GCVE-0-2026-108377)

Vulnerability from nvd – Published: 2026-10-13 17:22 – Updated: 2026-10-13 17:49

Title

dataclasses-avroschema allows code injection through generated Meta.schema_name

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.62.3 through 0.70.5, ClassRepresentation.render_metaclass inserts a schema-controlled Avro record name into the quoted Meta.schema_name field of generated Python source without escaping it. A crafted name can terminate the string literal and inject statements into the generated class body, which execute when the generated module is imported. Version 0.70.6 fixes the vulnerability by escaping schema values rendered into generated string literals.

Severity

8.8 (High)

CVE-2026-108376 (GCVE-0-2026-108376)

Vulnerability from nvd – Published: 2026-10-13 17:17 – Updated: 2026-10-13 17:24

Title

dataclasses-avroschema allows code injection through record names in generated default factories

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.47.3 through 0.70.5, FieldRepresentation.get_field_default inserts a schema-controlled referenced record name into the callable position of a generated default_factory lambda without validating it as an Avro name. A crafted record name can become an arbitrary Python expression that executes when an instance of the generated model consumes the field default. Version 0.70.6 fixes the vulnerability by rejecting record names that do not match the Avro name grammar.

Severity

8.8 (High)

CVE-2026-108375 (GCVE-0-2026-108375)

Vulnerability from nvd – Published: 2026-10-13 17:05 – Updated: 2026-10-13 17:27

Title

dataclasses-avroschema allows code injection through generated field-default literals

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, FieldRepresentation.get_field_default inserts schema-controlled string, UUID, bytes, and fixed field defaults into quoted literals in generated Python source without escaping them. A crafted default can terminate the literal and inject statements into the generated module, which execute when the module is imported. Version 0.70.6 fixes the vulnerability by escaping schema values rendered into generated string literals.

Severity

8.8 (High)

CVE-2026-108385 (GCVE-0-2026-108385)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:56 – Updated: 2026-10-13 18:15

Title

dataclasses-avroschema enum symbols can inject statements through generated member names

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, BaseGenerator.parse_enum and EnumRepresentation.render_symbols use each schema-controlled enum symbol as a generated enum member name after case conversion but without validating it as an identifier. When generator classes are used directly, newlines and punctuation can inject constrained statements into the generated enum class body, allowing namespace modification or preventing the module from loading. Version 0.70.6 fixes the vulnerability by validating every enum symbol as a name.

Severity

CVE-2026-108384 (GCVE-0-2026-108384)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:53 – Updated: 2026-10-13 20:21

Title

dataclasses-avroschema allows code injection through fixed-type aliases supplied as a bare string

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, BaseGenerator.parse_fixed interpolates a fixed type's aliases value directly into a generated types.confixed annotation. A list is represented with quoted entries, but a bare string is emitted as an unquoted Python expression and evaluated when the generated module is imported, allowing arbitrary code execution from a crafted schema. Version 0.70.6 fixes the vulnerability by rejecting aliases values that are not lists.

Severity

8.8 (High)

CVE-2026-108383 (GCVE-0-2026-108383)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:47 – Updated: 2026-10-14 15:58

Title

dataclasses-avroschema enum field defaults can inject statements into generated modules

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, FieldRepresentation.get_field_default renders a schema-controlled enum field default as an enum member reference after applying case conversion but without validating it as an identifier. Newlines, operators, and punctuation can escape the intended reference and inject constrained statements into the generated module, allowing namespace modification or preventing the module from loading. Version 0.70.6 fixes the vulnerability by validating enum defaults as names.

Severity

8.8 (High)

CVE-2026-108382 (GCVE-0-2026-108382)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:44 – Updated: 2026-10-13 18:00

Title

dataclasses-avroschema allows code injection through generated enum-symbol string literals

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, EnumRepresentation.render_symbols concatenates each schema-controlled enum symbol between double quotes in a generated enum assignment. When generator classes are used directly, a quote can terminate the string literal and inject arbitrary Python code into the enum class body, which executes when the generated module is imported. Version 0.70.6 fixes the vulnerability by escaping enum symbol values before rendering them.

Severity

8.8 (High)

CVE-2026-108381 (GCVE-0-2026-108381)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:43 – Updated: 2026-10-13 17:43

Title

dataclasses-avroschema pydantic-class metadata allows code injection in generated annotations

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.44.0 through 0.70.5, the Pydantic and AvroDantic model generators insert a schema field's pydantic-class value after pydantic. in a generated field annotation without safely restricting the expression. Because annotations are evaluated when the generated module is imported, a crafted value can execute arbitrary Python code. Version 0.70.6 fixes the vulnerability by restricting the value to a bare name or a call to a bare name with literal arguments.

Severity

8.8 (High)

CVE-2026-108380 (GCVE-0-2026-108380)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:41 – Updated: 2026-10-13 18:17

Title

dataclasses-avroschema field documentation allows code injection in generated Pydantic descriptions

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.65.9 through 0.70.5, PydanticFieldRepresentation.add_field_properties inserts a schema field's doc value between the quotes of a generated pydantic.Field description argument without escaping it. A crafted quote can terminate the string and inject an expression evaluated during generated class definition, allowing arbitrary Python code execution for Pydantic and AvroDantic model generation. Version 0.70.6 fixes the vulnerability by escaping the documentation value before rendering it.

CVE-2026-108379 (GCVE-0-2026-108379)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:40 – Updated: 2026-10-13 20:21

Title

dataclasses-avroschema fixed namespaces allow code injection in generated annotations

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, BaseGenerator.parse_fixed inserts a fixed type's namespace value between quotes inside a generated types.confixed annotation without escaping or validating it. A crafted quote can terminate the namespace string and alter the surrounding annotation expression, which Python evaluates when the generated class is defined, allowing arbitrary code execution. Version 0.70.6 fixes the vulnerability by requiring the namespace to be a dot-separated sequence of valid Avro names.

Severity

8.8 (High)

CVE-2026-108378 (GCVE-0-2026-108378)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:34 – Updated: 2026-10-14 15:55

Title

dataclasses-avroschema record documentation can terminate generated class docstrings

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.40.0 through 0.70.5, ClassRepresentation.render_docstring copies a schema record's doc value into a generated triple-double-quoted class docstring without escaping quotes or backslashes. A crafted triple-quote sequence can close the docstring and inject statements into the generated class body, while a trailing backslash can escape the generated closing delimiter, allowing Python code execution during module import. Version 0.70.6 fixes the vulnerability by escaping quotes, backslashes, and unsafe control characters before rendering docstrings.

Severity

8.8 (High)

CVE-2026-108377 (GCVE-0-2026-108377)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:22 – Updated: 2026-10-13 17:49

Title

dataclasses-avroschema allows code injection through generated Meta.schema_name

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.62.3 through 0.70.5, ClassRepresentation.render_metaclass inserts a schema-controlled Avro record name into the quoted Meta.schema_name field of generated Python source without escaping it. A crafted name can terminate the string literal and inject statements into the generated class body, which execute when the generated module is imported. Version 0.70.6 fixes the vulnerability by escaping schema values rendered into generated string literals.

Severity

8.8 (High)

CVE-2026-108376 (GCVE-0-2026-108376)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:17 – Updated: 2026-10-13 17:24

Title

dataclasses-avroschema allows code injection through record names in generated default factories

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.47.3 through 0.70.5, FieldRepresentation.get_field_default inserts a schema-controlled referenced record name into the callable position of a generated default_factory lambda without validating it as an Avro name. A crafted record name can become an arbitrary Python expression that executes when an instance of the generated model consumes the field default. Version 0.70.6 fixes the vulnerability by rejecting record names that do not match the Avro name grammar.

Severity

8.8 (High)

CVE-2026-108375 (GCVE-0-2026-108375)

Vulnerability from cvelistv5 – Published: 2026-10-13 17:05 – Updated: 2026-10-13 17:27

Title

dataclasses-avroschema allows code injection through generated field-default literals

Summary

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.38.0 through 0.70.5, FieldRepresentation.get_field_default inserts schema-controlled string, UUID, bytes, and fixed field defaults into quoted literals in generated Python source without escaping them. A crafted default can terminate the literal and inject statements into the generated module, which execute when the module is imported. Version 0.70.6 fixes the vulnerability by escaping schema values rendered into generated string literals.
