CVE-2026-19011Public exploitNetwork attack vector

Unauthenticated local file disclosure via prompt_file

Published Aug 6, 2026 · Updated Aug 6, 2026

External path control in TinyAGI 0.0.20 allows remote attackers to read local files through the unauthenticated agent API. The agent update route persists an unchecked prompt_file path, which buildSystemPrompt passes to fs.readFileSync and appends to an outbound provider prompt. Exposure requires network access to the HTTP API and filesystem read permission for the TinyAGI process; disclosed contents are sent to the configured model provider.
