  "works": "Prescreen clean (pypi 2.45.7 + github docling-project/docling.rs). Installed wheels only inside sandbox-run (no install.sh, no --download-models). Driven with official MCP Python SDK ClientSession StdioClientTransport (mcp 1.x/2.3.0) via python -m docling_rs.mcp --root \u2026 (not the hand JSON-RPC client). initialize \u2192 serverInfo docling-rs / docling.rs 2.45.7, protocol 2025-11-25. tools/list: convert, convert_to_markdown, list_input_formats (read_only_hint true). convert_to_markdown / convert worked on: 5-page text-layer PDF with a table (MARKER_P* present; pages=\"2-3\" kept only P2/P3), 400-page PDF (~395 KB md in 0.19 s), DOCX with unicode heading + table, XLSX as markdown table, HTML with unicode/Hebrew/emoji + table, unicode filename \ud55c\uae00 \ud30c\uc77c \ud83d\ude80.md (path and percent-encoded file: URI), chunks JSON, extensionless HTML. Bad inputs failed closed with clear errors (empty/garbage/truncated DOCX/PDF, empty uri, directory, missing file, unknown to=). --root escapes all failed closed (no CANARY_OUTSIDE_42): ../ traversal, deep .., absolute outside and /etc/passwd, absolute root/../outside, sibling-prefix root2, /proc/self/root and /proc/self/cwd, symlinks (relative, absolute, dir, nested), percent-encoded .. in file: URIs, file:  outside / localhost / FILE:// / file: single-slash / file: relative, file:  with remote host refused, leading-space absolute, options xbrl_taxonomy / ebcdic_layout outside root and asr_model with .. . Symlinked --root (rootlink\u2192root) still served in-root files and refused escapes. URL fetch off: http/https/mixed-case/leading-space refused; listener on :18777 got zero hits; data: HTML converted without fetching file:  or remote imgs; vlm_endpoint and use_web_browser refused without --allow-url-fetch; image_sources=remote with fetch off fell back to placeholders (no network). With --allow-url-fetch, loopback/localhost/10.0.2.100/decimal 2130706433/169.254.169.254 all refused as private/loopback (listener still zero hits); sandbox DNS maps example.com to 198.18.0.1 so public fetch also refused here. HTML/Markdown image_sources=local embedded only in-root inpic.png, not ../outside or file: outside. ODT draw:image xlink:href to outside absolute/file:  / ../outside did not leak with image_sources local/embedded.

Contradicts docs/SECURITY.md MCP section ('Local reads are confined to --root') and README. Same class as GHSA-p944-4xh2-x776. 2) Markdown throughput collapses on many short lines: md1.md ~1 MB \u2192 1.1 s, md4.md ~4 MB \u2192 53.5 s, md8.md ~8 MB \u2192 134 s via MCP (library alone ~8 s for 4 MB); huge.md ~49 MB timed out at 600 s; paragraph-broken 4 MB was 0.3 s \u2014 line-count sensitive. 3) JSON origin.mimetype is always \"text/plain\" for pdf/docx/html/xlsx/odt (cosmetic metadata). 4) Untested: --download-models / layout OCR tables, --http bearer mode, password-protected docs, real public URL fetch outside this sandbox DNS.",

Real bug in a documented security path: SECURITY.md / README claim that local reads are confined to --root, but a DoclingDocument JSON under --root (json is listed by list_input_formats) whose picture.image.uri holds absolute file:  or absolute paths outside the root is accepted by convert(..., images=\"embedded\") and the outside file bytes appear in the Markdown/JSON output as data: URIs. Seen at runtime with canary PNG outside --root (convert_to_markdown uses placeholder so it does not leak; convert with images=embedded does). Same class as Python docling GHSA-p944-4xh2-x776. Happy-path conversion (DOCX/HTML/XLSX/multi-page PDF/unicode/tables) and primary --root path/file: symlink escapes all held; URL fetch stayed off and private IPs stayed blocked with --allow-url-fetch. Also: Markdown with many short lines is very slow (~1 MB/1 s, ~4 MB/53 s, ~8 MB/134 s via MCP; 49 MB timed out at 600 s) \u2014 quadratic-ish; JSON origin.mimetype is always text/plain across formats (cosmetic).",
