sec: bump vulnerable dependencies to resolve HIGH/CRITICAL CVEs

[scale-ballen]

Summary

Bump vulnerable Python dependencies via workspace overrides and uv lock --upgrade to resolve HIGH/CRITICAL vulnerabilities in the agentex and agentex-auth container images.

Dependency Changes

Package	Before	After	CVEs Resolved
aiohttp	3.12.15	3.13.5	CVE-2025-53643 (HIGH), CVE-2025-69226 (HIGH)
python-multipart	0.0.12	0.0.24	CVE-2026-24486 (MEDIUM)
starlette	0.46.2	1.0.0	CVE-2025-62727
fastapi	0.115.14	0.135.3	Transitive starlette fix
cryptography	—	46.0.7	Multiple
certifi	2025.8.3	2026.2.25	CA bundle update
uvicorn	0.35.0	0.44.0	Relaxed upper bound from <0.36
urllib3	1.26.20	2.6.3	Major version bump (1.x → 2.x)
pyjwt	2.10.1	2.12.1	Latest available
agentex-sdk	0.4.18	0.9.10	Latest available

What Changed

1. pyproject.toml (workspace root): Expanded override-dependencies to force patched versions of aiohttp, python-multipart, starlette, cryptography, certifi. Bumped agentex-sdk floor to 0.9.10.
2. agentex/pyproject.toml (backend): Bumped aiohttp floor to ≥3.13.5, python-multipart to ≥0.0.24, relaxed uvicorn upper bound (was <0.36).
3. uv.lock: Regenerated with uv lock --upgrade.

Testing Results

• Unit tests: 79/79 passed
• Fixture-dependent tests: 108 errors (pre-existing — require Docker/Postgres, not caused by this change)
• No import errors or resolution conflicts

Risk Assessment

• urllib3 1.x → 2.x: Major version jump. urllib3 2.x removes deprecated APIs but aiohttp/httpx abstract this. No direct urllib3 usage in agentex source code.
• starlette 0.46 → 1.0: Major version. Deprecated decorators removed. No usage of deprecated APIs found in codebase.
• uvicorn relaxed bound: Was pinned <0.36. Now allows latest (0.44.0). uvicorn follows semver — patch/minor bumps are safe.
• agentex-sdk 0.4.18 → 0.9.10: Large version jump. Same fastapi<0.116 constraint (overridden by workspace). SDK is a leaf dependency.

Notes

• agentex-sdk still pins fastapi<0.116 — the workspace override (fastapi>=0.135.0) is required
• This PR must merge before the parent agentex repo PR can merge (submodule reference)

Test Plan

• uv lock --upgrade resolves without conflicts
• Unit tests pass (79/79)
• No deprecated API usage found in codebase
• CI pipeline passes
• Docker build succeeds (FIPS and standard variants)
• Deploy to dev environment and verify service health

Greptile Summary

This PR bumps a set of Python dependencies to resolve HIGH and CRITICAL CVEs, using uv workspace-level override-dependencies to force patched versions regardless of the agentex-sdk's pinned constraints, then regenerates uv.lock. The approach is sound: overrides are correctly scoped, the lock file resolves without conflicts, and the starlette <2.0 upper bound guards against a future major version pulling in breaking changes.

Confidence Score: 5/5

Safe to merge — targeted security dependency bumps with no functional code changes, passing unit tests, and no deprecated API usage in the codebase.

All changes are dependency version pins and a regenerated lock file. The starlette imports in the codebase (BackgroundTask, BaseHTTPMiddleware, ASGIApp, TestClient, etc.) are all stable APIs present in starlette 1.0.0. No P0 or P1 findings identified.

No files require special attention.

Vulnerabilities

This PR is specifically a security remediation. All patched CVEs (aiohttp CVE-2025-53643/CVE-2025-69226, python-multipart CVE-2026-24486, starlette CVE-2025-62727) are addressed by the resolved package versions in uv.lock. No new secrets or auth-boundary changes were introduced. The cryptography and certifi overrides are appropriate belt-and-suspenders hardening. No new security concerns identified.

Important Files Changed

Filename	Overview
pyproject.toml	Adds five new override-dependencies (aiohttp, python-multipart, starlette, certifi, cryptography) and bumps agentex-sdk floor to 0.9.10; <2.0 guard on starlette is a good defensive bound.
agentex/pyproject.toml	Bumps aiohttp floor to >=3.13.5, python-multipart to >=0.0.24, and removes the overly-tight uvicorn <0.36 upper bound; all changes are consistent with the workspace overrides.
uv.lock	Auto-generated lock file regenerated with uv lock --upgrade; resolves aiohttp@3.13.5, starlette@1.0.0, fastapi@0.135.3, uvicorn@0.44.0, urllib3@2.6.3, cryptography@46.0.7, certifi@2026.2.25 with no conflicts.
