Python EUVD-2026-50067

We are generating a synthetic analysis for CVE-2026-54654. We have a lot of data: description, CVSS, CWE, tags, references, GHSA advisory with detailed description, PoC, patch commit details, CPE. Need to produce JSON fields as instructed.

Fields: product_name, summary, technical_context, risk_assessment, affected_products, remediation, exploit_scenario, exploitation_conditions, attack_chain, confidence_notes, prevalence, prevalence_basis, assessed_cvss_vector, assessed_cvss_rationale, assessed_cvss40_vector.

Let's extract key info:

• Product: "datamodel-code-generator" (pip package, from koxudaxi). Product name should be 1-3 words: "datamodel-code-generator".
• Description: Code injection via unescaped carriage return in --extra-template-data comment field, fixed in 0.60.2.
• CVSS: 7.8, vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
• CWE-94: Code Injection.
• Tags: Python, RCE, Code Injection, Datamodel Code Generator.
• KEV: not mentioned, assume not in KEV. POC: mentioned in advisory (secret gist). But we can't confirm if it's public or private secret gist; the advisory says "Complete self contained POC is available at my secret gist", so the reporter likely privately shared with maintainers? Or the link is there? Since the GHSA description says "PoC available at my secret gist: https://...", but the URL is there. It's a public gist? Might be public. But we don't have explicit POC=YES flag. The tags don't say POC available. Advisory text includes PoC section but the URL is given. Could be public. We'll treat as "publicly available exploit code exists" since the gist URL is embedded in the advisory and likely accessible to anyone who reads it. However, we must be careful: the description says "Complete self contained POC is available at my secret gist" - "secret" might indicate private. But it's in a public security advisory, so it's exposed. It's not a standard public POC, but I'll note it as possible public POC. The instructions say: if POC=YES but no
