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-2026-54654 exists.\n\nAffected packages and fixed versions:\n- datamodel-code-generator (PyPI): affected from 0.14.1; fixed in 0.60.2\n- datamodel-code-generator (PyPI): affected from 0.14.1; fixed in 0.60.2\n- datamodel-code-generator (PyPI): affected from 0.14.1; 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-2026-54654/ (Markdown: https://insights.sbomify.com/CVE-2026-54654/index.md)","id":"CVE-2026-54654","markdown":"https://insights.sbomify.com/CVE-2026-54654/index.md","name":"CVE-2026-54654","record":{"aliases":["GHSA-wjv6-jcfj-mf9r","MINI-rfqh-p392-g9cv","PYSEC-2026-3566"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Python code generator","requires_auth":"none","summary":"Attackers can inject Python code into generated models via unescaped carriage returns in template data, leading to code execution upon import.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"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"},{"id":"CWE-1336","name":"Improper Neutralization of Special Elements Used in a Template Engine"}],"description":"datamodel-code-generator generates Python data models from schema definitions.
