From 910a54ff40b04c6f6d21446d7d9a37f1956e93a2 Mon Sep 17 00:00:00 2001 From: seonghobae <8172694+seonghobae@users.noreply.github.com> Date: Fri, 3 Jul 2026 21:51:19 +0000 Subject: [PATCH] =?UTF-8?q?=F0=9F=9B=A1=EF=B8=8F=20Sentinel:=20[CRITICAL]?= =?UTF-8?q?=20Fix=20Resource=20Exhaustion=20DoS=20in=20/parse=20endpoint?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The `/parse` API buffered the entire contents of an uploaded PDF file into a single in-memory `bytes` object (up to 20MB) by calling `await file.read(...)`. This created a critical Resource Exhaustion Denial of Service (DoS) vulnerability, where multiple concurrent uploads could quickly exhaust the server's memory. This fix refactors the `/parse` endpoint to incrementally stream the uploaded file chunks directly to a temporary file on disk using `await file.read(8192)`. The structural `_validate_pdf_structure` checks and downstream MinerU processing logic now safely operate against the bounded temporary file instead of an unbounded in-memory variable, capping the memory footprint to the 8KB chunk size per request. --- .jules/sentinel.md | 4 ++ src/newsdom_api/main.py | 54 +++++++++++++++++---------- src/newsdom_api/service.py | 23 ++++++++++-- src/newsdom_api/synthetic.py | 4 +- tests/test_benchmark_ocr.py | 8 +--- tests/test_derive_private_baseline.py | 16 ++------ tests/test_errors.py | 5 ++- tests/test_parse_endpoint.py | 52 ++++++++++++++------------ tests/test_parse_endpoint_success.py | 9 +++-- tests/test_schemas.py | 5 ++- tests/test_tools_batch_parse.py | 4 +- tools/batch_parse_pdf.py | 8 +++- tools/export_markdown.py | 8 +++- tools/parse_pdf.py | 4 +- 14 files changed, 125 insertions(+), 79 deletions(-) diff --git a/.jules/sentinel.md b/.jules/sentinel.md index 18667ffe..d1db5592 100644 --- a/.jules/sentinel.md +++ b/.jules/sentinel.md @@ -36,3 +36,7 @@ **Vulnerability:** Unhandled FastAPI exceptions can produce sanitized 500 responses without the same defense-in-depth headers applied by normal middleware responses. **Learning:** Error response paths need explicit coverage because exception handlers can bypass or duplicate header logic differently from successful request paths. **Prevention:** Route both middleware responses and global 500 exception responses through a shared security-header helper. +## 2026-06-30 - Fix Resource Exhaustion DoS via In-Memory File Buffering +**Vulnerability:** The `/parse` endpoint buffered entire client file uploads into an unbounded `bytearray` inside Python memory via `await file.read(MAX_PARSE_UPLOAD_BYTES)` before structural checks.
