  "details": "Hugo Blog is a tech blog site. In commit 744ca15 and prior, the AI assistant proxy exposes three HTTP endpoints (POST /api/blog-assistant, POST /api/blog-search-embedding, POST /api/blog-search-rerank) without any authentication check. When deployed following the documented Nginx reverse-proxy setup, any unauthenticated remote attacker can send arbitrary requests that the proxy forwards to the upstream LLM/embedding/rerank API using the operator's server-side API key (OPENAI_API_KEY / AI_SEARCH_API_KEY). This enables unlimited quota consumption, cost exhaustion, and potential service unavailability for the operator. At time of publication, there are no publicly available patches.",
