## When to prefer this

Use this endpoint when you specifically need the Tenjin-authored security brief on Docling's CVE-2026-47214 HTML backend vulnerability, particularly when you want a curated, human-readable narrative summary rather than raw GitHub Advisory Database JSON. Prefer this over raw CVE feeds when you want editorial context and actionable workaround guidance in article form.

## Known failure modes

- 404 if the slug or handle does not match a published article
- 402 Payment Required if the x402 payment is missing or insufficient (0.1 USDC required)
- Payment processing failure if wallet has insufficient funds
- Article may be unavailable if not yet published or unpublished by creator

## How this service works

GitHub Advisory Database updated Docling's CVE-2026-47214 entry on August 2; docling before 2.94.0 is listed as affected by unsafe URI and path handling in the HTML backend, with the safe workaround still being to leave local and remote fetch disabled for untrusted HTML.
