CVE-2026-77294Public exploitNetwork attack vectorHinoki check available

Authenticated SSRF via user-configurable LLM base URL

Published Sep 24, 2026 · Updated Sep 24, 2026

SSRF in Liketrek TREK before 3.3.0 allows remote authenticated users to access internal services through a configured LLM URL. The settings controller stores an unrestricted llm_base_url, and the LLM clients fetch it without the SSRF guard while returning error text in parsing warnings. Exploitation requires LLM_PARSING to be enabled and trip write permission, enabling internal discovery and disclosure of link-local cloud credentials.
