It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-54656 exists.\n\nAffected packages and fixed versions:\n- datamodel-code-generator (PyPI): affected from 0.52.1; fixed in 0.60.2\n- datamodel-code-generator (PyPI): affected from 0.52.1; fixed in 0.60.2\n- datamodel-code-generator (PyPI): affected from 0.52.1; fixed in 0.60.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-54656/ (Markdown: https://insights.sbomify.com/CVE-2026-54656/index.md)","id":"CVE-2026-54656","markdown":"https://insights.sbomify.com/CVE-2026-54656/index.md","name":"CVE-2026-54656","record":{"aliases":["GHSA-8m8r-38jm-f355","PYSEC-2026-3559"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Python code generator","requires_auth":"none","summary":"Attackers can execute arbitrary Python code by injecting malicious validators into generated Pydantic models via the extra-template-data option.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"datamodel-code-generator","vendor":"koxudaxi"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"datamodel-code-generator generates Pydantic v2 models, dataclasses, TypedDict, and msgspec.Struct from OpenAPI, JSON Schema, GraphQL, Avro, Protobuf, and raw JSON, YAML, or CSV.
