fix(deps): require aiohttp >=3.14.1 for VULN-88795

[shuningc]

Summary

Fixes VULN-88795 by upgrading transitive aiohttp to ≥3.14.1 (lock resolves 3.14.2).

aiohttp ≤3.14.0 allows a TLS SNI server_hostname bypass on reused connections (fixed in 3.14.1).

What changed

1. poetry.lock — regenerated from current main + vcrpy ^8.3.0:

urllib3 → 2.7.0 (was 2.5.0 on the branch — the reviewer was right)
aiohttp → 3.14.3 (via vcrpy bump)
vcrpy → 8.3.0
2. Example pins aligned (both files touched by this PR):

examples/agent/minimal-agent-example/requirements.txt: urllib3==2.6.3 → 2.7.0
examples/agent/startup-simulator-3000/requirements.txt: urllib3==2.6.3 → 2.7.0
3. Reverted accidental pyproject.toml ruff churn — PR diff is back to only vcrpy ^7.0.0 → ^8.3.0.

Key problems

[Major] Description ≠ diff. The title/summary claim a direct floor aiohttp = ">=3.14.1,<4" was added "following the idna/filelock convention." Neither is
true — pyproject.toml has no aiohttp entry (grep → 0), and no idna/filelock floors exist. The commit history shows this: cda63c0 added a direct requirement, then 8025a47 reverted to "keep aiohttp transitive, bump lock only." The description still describes the abandoned approach.

[Major] "Only aiohttp changed" is false. The lock also bumps urllib3 1.26.20 → 2.5.0 (a major version jump), bumps vcrpy 7 → 8.3.0, and drops types-requests/types-urllib3. The urllib3 2.x transition shouldn't be hidden behind an "only aiohttp" claim — it should be a conscious decision.

[Minor] Version drift: locks say 3.14.2, example requirements.txt files pin 3.14.1. Both safe, but avoidable inconsistency.

[Minor] startup-simulator-3000/requirements.txt bumps aiohttp but carries none of aiohttp 3.14's supporting deps (yarl/multidict/propcache) — worth a pipinstall -r smoke test.

The changes needed are accuracy and consistency, not code logic. The vcrpy bump is legitimate and necessary. Fix the title/description to match the transitive approach, confirm the urllib3 major bump is intentional, and reconcile the pin mismatch.

Verdict: request_changes — Lock regeneration downgrades urllib3 2.7.0→2.5.0 (reintroduces VULN-88814/CVE-2026-21441) plus cryptography, pillow, protobuf, click, python-multipart; an example's install is also broken.

General Comments

• 🔴 critical (security): poetry.lock downgrades urllib3 from 2.7.0 → 2.5.0 (see diff around the urllib3 stanza: the merge base had a non-PyPy version = "2.7.0" entry, HEAD collapses to a single version = "2.5.0"). urllib3 is a core dependency (optional = false, groups main/test), so this is not behind an extra. Downgrading to 2.5.0 reintroduces CVE-2026-21441 — the decompression-bomb issue on redirect responses — which is exactly VULN-88814 (remediation ≥2.6.3/2.7.0). This PR is a security fix that simultaneously regresses another security fix that main had already applied.

The PR description states "This PR does not intentionally upgrade urllib3 for CPython — 2.5.0 was already in the lock." That is contradicted by the diff: the base had 2.7.0 for CPython. Please regenerate the lock from current main so urllib3 stays at ≥2.7.0 (or explicitly pin urllib3 = ">=2.7.0" / >=2.6.3). This must be resolved before merge — otherwise merging closes VULN-88795 while reopening VULN-88814.

• 🟠 major (security): The lock regeneration produced broad, unexplained downgrades well beyond aiohttp/vcrpy: cryptography 49.0.0 → 45.0.6, pillow 12.3.0 → 11.3.0, protobuf 6.33.6 → 6.31.1, click 8.4.2 → 8.1.8, python-multipart 0.0.32 → 0.0.20, and cffi 2.x removed in favor of 1.17.1. Several of these (pillow, cryptography, python-multipart) are security-sensitive packages where downgrading can reopen fixed CVEs. This pattern strongly suggests the lock was regenerated in an environment divergent from current main (different index state / resolver inputs) rather than a clean rebase. Please regenerate poetry.lock from an up-to-date main checkout and confirm the diff contains only the intended aiohttp (+vcrpy) changes; the downgrade churn should disappear. As-is, the claim that only aiohttp/vcrpy changed is inaccurate and the collateral downgrades are a merge risk.

Follow-ups

Suggested follow-up work that could be tracked as Shortcut stories:

• examples/agent/startup-simulator-3000/requirements.txt:3-57: aiohttp is listed twice (line 3 pinned ==3.14.2 and line 57 bare aiohttp). Deduplicate to a single pinned entry to avoid confusion in the requirements file.

Verdict: needs_discussion — Lock resolves aiohttp 3.14.3 and closes the CVE, but the fix isn't enforced by any version floor and the PR description is materially inaccurate about the ruff changes.

General Comments

• 🟠 major (security): The security remediation is not enforced by any version constraint. The PR title says "require aiohttp >=3.14.1", but pyproject.toml has no aiohttp entry (it remains a transitive dep of the crewai/all extras and of vcrpy's resolution). The lock currently resolves 3.14.3, which does close CVE-2026-54275 for now — but nothing prevents a future poetry lock regeneration (or resolution on a different platform/Python) from re-selecting an aiohttp < 3.14.1 that still satisfies its parents, silently reintroducing the SNI-bypass vuln. For a security ticket with a due date, consider adding an explicit floor (e.g. aiohttp = ">=3.14.1") so the remediation is durable and self-documenting. The previous reviewer raised this and the author chose "keep aiohttp transitive, bump lock only" — please confirm that's a conscious, accepted trade-off for a security fix rather than an oversight.
• 🟡 minor (design): Version drift across the changed files: the main poetry.lock resolves aiohttp 3.14.3, while examples/agent/langgraph-fsi-agent/before/poetry.lock and both example requirements.txt files pin 3.14.2. All are ≥3.14.1 so all are safe, but the inconsistency is avoidable — regenerating the examples against the same resolution (or vice versa) would keep them aligned.

Follow-ups

Suggested follow-up work that could be tracked as Jira tickets:

• examples/agent/startup-simulator-3000/requirements.txt:57-57: Pre-existing: this file pins every dependency except aiohttp's supporting libs (aiohappyeyeballs, aiosignal, multidict, propcache, yarl, frozenlist are absent), and carries a duplicate bare aiohttp on the last line. Not broken (pip will resolve the unpinned transitive deps freely), but inconsistent with the otherwise-frozen file. Worth a pip install -r smoke test and removing the stray duplicate line.
• examples/rag/cli-rag-demo/requirements.txt:7-8: Not touched by this PR, but this example still pins aiohttp==3.11.12 with aiohappyeyeballs==2.4.6/aiosignal==1.3.2 and urllib3==2.6.3. If these examples are in scope for the same CVE remediation, they should be bumped too; if not, confirm they're intentionally excluded. Same applies to examples/rag/elastic-chatbot-rag-app/requirements.txt (aiohttp==3.11.14).

[fercor-cisco]

🟡 minor (documentation): These ruff per-file-ignores changes (tests/**/*.py → tests/** and the new PLC0415 ignore) are unrelated to the aiohttp/vcrpy security bump, and they directly contradict PR description point 3, which claims "Reverted accidental pyproject.toml ruff churn — PR diff is back to only vcrpy ^7.0.0 → ^8.3.0." The churn was not reverted — it's still in the diff. Either drop these lines to keep the security PR focused, or update the description and keep them as a deliberate, separately-justified change.
