  • Makes URLReadTool read files served as application/octet-stream from an extensionless URL. Content type now resolves in three steps — Content-Type header, then URL path extension, then the already-fetched body's magic bytes — where each step runs only if every earlier one returned nothing, and none may override an earlier answer. That ordering makes the sniff a pure widening: it can turn a refusal into a read, never a read into a different read.
  • Adds an XLSX extractor. The reported file is a spreadsheet, so sniffing alone identified it as OOXML but had nowhere to send it — URLReadTool would have refused it even with a correct spreadsheetml Content-Type. Uses openpyxl, already a core crewai dependency, so no new dependency. Sheets render as CSV under a Sheet <name>: heading, mirroring the PDF extractor's per-page shape.
  • Public surface: the agent-facing description gains XLSX, and tool.specs.json is regenerated (2 lines). No signature change to safe_get_bounded — its (body, content_type, final_url) 3-tuple and both callers (url_read_tool.py, rag/loaders/pdf_loader.py) are untouched, so nothing that imports it breaks.
  • Preserved: a usable Content-Type is still authoritative and still returns None for image/png; the URL-extension fallback still runs, for both the final and the requested URL, ahead of the sniff. Both are pinned by explicit precedence tests. All 45 pre-existing tests pass unedited.
  • Fails closed by design, and each rule is mutation-tested — the rule was deliberately broken and a test confirmed to fail. A zip is DOCX only if word/document.xml is in its central directory and XLSX only if xl/workbook.xml is (namelist() reads the directory, never decompresses, so a zip bomb costs nothing). Text requires a strict, whole-body UTF-8 decode with no NUL byte — a prefix decode would split a multi-byte character, and latin-1/UTF-16 are refused rather than rescued into mojibake. An empty body identifies nothing. Without the DOCX gate, the actual reported file produced Error: Failed to read DOCX content; with it, an honest refusal — verified against the real bytes.
  • Tests: 79 passing, 34 new (121 test lines vs 77 production). Covers PDF/DOCX/XLSX/HTML/CSV/JSON sniffing, BOM and leading whitespace before an HTML prefix, xlsx CSV-quoting of embedded commas/quotes/newlines, trailing phantom-row trimming, uncalculated formulas, .pptx/.vsdx/plain-zip refusal, malformed and truncated zips, and the two precedence invariants. Only the sync run() path exists — URLReadTool does not override _arun, unchanged by this PR.
  • No docs change: URLReadTool has no page under docs/edge/, only a changelog mention.
  • Keeps this intentionally small: no Content-Disposition parsing, no safe_get_bounded signature change, no PPTX or legacy .doc/.xls extractor (PPTX would need a new python-pptx dependency), no reading of response-content-* query params, no charset-guessing rescue for non-UTF-8 text.
  • Next: DataTypes.from_content (rag/data_types.py:100-154) routes this same presigned URL to WebPageLoader pre-fetch and returns raw %PDF-1.7… as "webpage text" with no error — a silent wrong answer that needs its own ticket. rag/loaders/docx_loader.py:44-50 also downloads via unbounded safe_get with no max_bytes ceiling.

Verified: ruff check lib/ and ruff format --check lib/ clean (917 files); mypy clean for the changed file (the 6 pre-existing errors are in crewai/rag/embeddings/providers/ibm/, identical on main); end-to-end run against the real reported URL now returns the spreadsheet, and a local-socket run covers PDF/DOCX/CSV/HTML success plus XLSX-shaped and PNG refusal through the real safe_get_bounded.

Not verified: test_search_tools.py fails on this branch, but it fails identically (in fact more: 5 vs 4) on main with the branch stashed — pre-existing and unrelated. I did not test any provider/streaming path because none exists here. I have not measured resource amplification in the newly-reachable extractors; where an object store pins octet-stream and an untrusted party supplies the bytes, sniffing newly lets that uploader reach pymupdf/python-docx/openpyxl/bs4 — bounded, since a hostile server can already reach all four today by simply declaring the Content-Type, but naming it rather than glossing it.

Note

Medium Risk
URL fetching now runs sniffing and XLSX parsing on untrusted bytes (with new bounds but not uniform zip decompression limits across extractors), alongside dependency bumps that affect optional extras.

Overview
URLReadTool now resolves format in order: Content-Type, URL extension, then byte sniffing on the fetched body. That unblocks presigned/share links served as application/octet-stream with no path extension (S3, R2, SharePoint, etc.). Sniffing is fail-closed (PDF magic, OOXML zip markers for DOCX/XLSX only, strict UTF-8 text/HTML) and cannot override an earlier decision.

XLSX is added: sheets are emitted as CSV under Sheet <name>: headings via openpyxl, with scan/output cell budgets and truncation messaging to limit padded-dimension DoS. Tool descriptions and tool.specs.json mention XLSX and presigned-link behavior.

browser_toolkit replaces cast(Tag, …) with isinstance checks when parsing links.

Dependency/security pins are tightened in workspace and crewai-tools extras: gitpython>=3.1.59, snowflake-sqlalchemy>=1.11.0, beautifulsoup4>=4.13.4,<5, and a Python-version-split unstructured floor for the [xml] extra (0.24+ on 3.11+). Extensive new url_read_tool tests cover sniffing, XLSX edge cases, and precedence.

Bot review triage (4 findings, all with a stated position):

  • Bugbot — XLSX padded dimensionsfixed (ea705090f). Reproduced worse than reported: a 4.8 KB workbook with one cell at B100000 produced 100,000 rows / 200,000 cells, and the trailing-only trim removed none of them because the stray cell keeps the last row non-empty. Rows now skip as they stream; _XLSX_MAX_CELLS bounds output with a visible truncation notice.
  • CodeRabbit — ZIP matching both OOXML markersfixed (ea705090f). Two identities is not a positive identification; refused.
  • CodeRabbit — whitespace-only cell valuesfixed (4ab2cdd64). Padding arrives as None"" exactly, so testing exactly-empty keeps the amplification fix and stops deleting author-entered spaces; rstrip("\n") instead of rstrip() preserves a trailing space in the final cell. Hoisted out of the f-string — a backslash in an f-string expression is a SyntaxError on 3.10/3.11.
  • CodeRabbit — XLSX decompression DoS (Major)partially fixed, remainder deferred. The sheet-expansion half is fixed above. ZIP decompression-ratio limits are not in this PR: .docx already reached python-docx and PDFs already reached pymupdf on main, so bounding only openpyxl would be theatre. Needs a Linear ticket for a uniform decompression bound across all three extractors.

CI note: tests initially failed on tests/tracing/test_trace_enable_disable.py (VCR cassette miss → ConnectionError). Re-running the failed jobs on identical code passed on 3.10/3.11/3.12/3.13, and CI's exact shard (cd lib/crewai && pytest --splits 8 --group 5) passes locally (662 passed). That test imports only crewai/pytest/tests.utils — no crewai_tools — and this PR touches only lib/crewai-tools. pip-audit failures are on snowflake-sqlalchemy/unstructured; git diff main..HEAD -- '**/pyproject.toml' uv.lock is empty, so this PR changes no dependency.

URLReadTool resolved content type from the Content-Type header and then
the URL path extension. Presigned object-store links carry neither: they
pin every object to application/octet-stream and use a content hash for a
path, so a SharePoint download landing in R2 was refused outright.

Sniff the already-fetched body as a third source, consulted only after the
header and both URL extensions come back with nothing. The sniff can turn
a refusal into a read but never a read into a different read, so no URL
that works today changes behavior.

Fails closed: a zip is DOCX only when word/document.xml is in its central
directory, so an .xlsx keeps its honest refusal instead of surfacing a
misleading "failed to read DOCX"; text requires a strict, whole-body UTF-8
decode with no NUL byte; an empty body identifies nothing.

The reported presigned SharePoint link is a spreadsheet, so sniffing the
body identified it as OOXML but still had nowhere to send it: URLReadTool
had no XLSX extractor, and the file would have been refused even with a
correct spreadsheetml Content-Type.

Read workbooks with openpyxl, already a core crewai dependency, so this
adds no new one. Sheets are emitted as CSV under a "Sheet <name>:" heading,
mirroring the PDF extractor's per-page shape. read_only streams the sheets
instead of building the whole object graph and data_only takes cached
values, both of which matter for a workbook arriving from an untrusted URL.

Cells are written through csv rather than joined, so a comma, quote or
newline inside a cell cannot corrupt the grid, and trailing phantom rows
are trimmed because Excel reports sheet dimensions generously.

📝 Walkthrough

Walkthrough

The URL read tool now detects content from response bytes when headers and URL extensions are insufficient. It supports bounded XLSX extraction as CSV text with cached values and truncation reporting. Hyperlink parsing, dependency constraints, and package overrides are also updated.

Changes

URL read enhancements

Layer / File(s) Summary
Byte-based type resolution
lib/crewai-tools/src/crewai_tools/tools/url_read_tool/url_read_tool.py
The tool resolves types from declared content types, URL extensions, and response bytes. It detects PDF, DOCX, XLSX, HTML, and UTF-8 text. It refuses invalid, unsupported, empty, or ambiguous content.
Bounded XLSX extraction
lib/crewai-tools/src/crewai_tools/tools/url_read_tool/url_read_tool.py
The tool loads XLSX workbooks with cached values and renders worksheet rows as CSV. It preserves whitespace, omits blank padded rows, limits emitted cells to 200,000, limits scanning to 5,000,000 cells, and reports truncation.
Validation and tool contract updates
lib/crewai-tools/tests/url_read_tool_test.py, lib/crewai-tools/tool.specs.json
Tests cover binary sniffing, XLSX formatting, malformed and ambiguous packages, workbook errors, truncation, and forged dimensions. Tool descriptions document XLSX support and byte-based fallback detection.

Hyperlink type safety

Layer / File(s) Summary
Hyperlink Tag validation
lib/crewai-tools/src/crewai_tools/aws/bedrock/browser/browser_toolkit.py
The synchronous and asynchronous hyperlink extractors skip non-Tag elements before reading text and href values.

Dependency constraint updates

Layer / File(s) Summary
Dependency and security constraints
lib/crewai-tools/pyproject.toml, pyproject.toml
The project widens the Beautiful Soup constraint, raises the GitPython minimum to 3.1.59, removes the GitPython package cutoff, and adds Python-version-gated overrides for Snowflake SQLAlchemy and Unstructured.

Merge Risk: 🟡 Moderate · up to 44bbc

This change adds fallback URL content detection and XLSX extraction, but scan-limit reporting and supported-format messaging remain incomplete. Python 3.10 installations may also retain an Unstructured version affected by the documented full-read SSRF advisory, so these issues should be resolved or explicitly accepted before merging.

Bot review found two real defects in the XLSX extractor, both reproduced.

openpyxl pads every row up to a sheet's declared dimension, so a single
stray cell far down the sheet turned a 4.8 KB upload into 100,000 rows and
200,000 cells. Trimming only trailing blanks did not help, because the
stray cell sits at the end and keeps the last row non-empty. Blank rows are
now skipped as they stream, and a cell budget caps what any one workbook
can hand an agent -- announced in the output rather than silently applied.

A zip carrying both word/document.xml and xl/workbook.xml was classified as
DOCX. Two identities is not a positive identification, so it is refused.

Bot review, verified: openpyxl's row padding arrives as None, so testing
cells for exactly-empty drops it just as well as .strip() did while leaving
a row whose cells the author really did fill with spaces. And rstrip() on
the rendered grid removed a trailing space from the final cell along with
the line terminator; only the terminator should go.

The cell budget only counted cells that reached the output, and blank rows
skip before that point. A sheet can declare Excel's maximum dimension while
holding two real cells; openpyxl then pads every row out to 16,384 columns
and yields one row per gap. Measured: a 4,848-byte workbook drove 1.64
billion cell normalizations in 15.2 seconds with the budget never touched.

Charge a separate scan budget per row, before the row is normalized and
before the blank check, so the work a hostile sheet can demand is bounded
whether or not any of it is emitted. The regression test asserts the read
completes in under 5 seconds and is mutation-verified: dropping the per-row
charge takes it back to 26 seconds.

Preserve the truncation notice when no rows were emitted.

When worksheet.iter_rows() exceeds scannable before emitting a row, _extract_xlsx sets truncated and leaves sheets empty. The early return then hides the truncation notice. Build the no-cells text first, then append the truncation marker. Add a regression test for a wide worksheet with its first nonblank cell beyond the scan budget.

gitpython 3.1.58 has PYSEC-2026-3785 through -3788, fixed in 3.1.59; the
lock now takes 3.1.61. Its exclude-newer-package cutoff is dropped rather
than bumped -- the global 3-day cutoff has long since passed 2026-08-05, so
that per-package pin was only holding the fix back.

snowflake-sqlalchemy 1.10.0 has GHSA-8g6f-qw9x-4q6q (SQL injection and
local file disclosure), fixed in 1.11.0.

unstructured 0.18.32 has GHSA-4mvj-m6j5-pmf7, a full-read SSRF via the url=
argument of partition(). The patched 0.24.0 requires Python >=3.11 while
crewai-tools supports 3.10, so the floor carries a marker and 3.10 stays on
the old line. 0.24+ also requires beautifulsoup4>=4.14.3, so the bs4 pin
widens from ~=4.13.4 to >=4.13.4,<5 -- a widening, so no existing install
breaks. uv resolves bs4 4.13.5 on 3.10 and 4.15.0 on 3.11+.

pip-audit locally: "No known vulnerabilities found, 5 ignored", with no new
--ignore-vuln entries. Only crewai-tools[xml] grows, gaining spacy and
openai-whisper transitively through unstructured's extras.

Widening the beautifulsoup4 pin let uv resolve 4.15.0 on Python 3.11+ while
3.10 stays on 4.13.5, because the old unstructured line holds it back there.
4.15 types find_all precisely, so cast(Tag, link) became redundant and mypy
failed the 3.11-3.13 type-checker jobs while 3.10 passed.

isinstance narrowing is correct under both versions and is what AGENTS.md
asks for anyway. Verified by running mypy against 4.15.0 and again against
4.13.5: browser_toolkit is clean under both, leaving only the pre-existing
errors in crewai/rag/embeddings/providers/ibm.

…ides

Bot review caught a regression I introduced. override-dependencies replace
the whole requirement including its marker, so gating the unstructured
override on python_version >= '3.11' dropped the dependency outright on
3.10: the lock held only 0.24.1, never the 0.18 line the comment claimed.
crewai-tools[xml] would have installed no unstructured at all there.

Move the floors into lib/crewai-tools/pyproject.toml, where a marker split
means what it says -- >=0.24.0 on 3.11+, >=0.17.2 below -- and drop the
root override for unstructured entirely. The lock now carries both 0.18.32
and 0.24.1 under complementary markers.

Same reasoning applies to the other two, per the nltk precedent already in
that file: a uv override only shapes this workspace's lock, so consumers
installing crewai-tools[snowflake] or [github] were still getting the
vulnerable floors. Declared there now as well.

Also documents the tool as a fit for presigned and share links from S3, R2,
Google Drive, OneDrive and SharePoint -- the case this PR fixes -- while
saying plainly that it reads a URL and does not authenticate.
