Summary

Remediates CVE-2026-34515 (open redirect vulnerability) in aiohttp by adding an explicit aiohttp>=3.13.4 dependency constraint to pyproject.toml. The lockfile already resolves aiohttp to version 3.13.5, which satisfies this constraint — no code changes were required.

Changes

pyproject.toml: Added aiohttp>=3.13.4 as an explicit dependency with an inline comment referencing CVE-2026-34515, ensuring the vulnerable version (3.13.3 and below) can never be installed, even if the lockfile is regenerated or the dependency is resolved transitively.
uv.lock: No changes required — the lockfile already resolves aiohttp to 3.13.5, which satisfies the new >=3.13.4 lower bound. Verified that the pinned version exceeds the minimum safe version.

Design Decisions

Explicit dependency over transitive: Rather than relying solely on the lockfile pin, aiohttp>=3.13.4 is declared as an explicit dependency in pyproject.toml. This documents the security requirement at the project manifest level, making it visible to future maintainers and preventing a lockfile regeneration or dependency resolution change from silently downgrading to a vulnerable version.
Minimum version constraint (>=3.13.4) rather than exact pin: Using a lower-bound constraint rather than an exact version (==3.13.5) allows future patch releases to be adopted without requiring a manual constraint update, while still blocking all known-vulnerable versions.
Inline CVE comment: A comment referencing CVE-2026-34515 is added alongside the constraint in pyproject.toml to provide traceability — reviewers and auditors can immediately understand why the constraint exists without consulting external issue trackers.
No code changes: CVE-2026-34515 is an open redirect vulnerability in aiohttp itself; the fix is entirely in the upstream library. No changes to application logic, request handling, or response construction were necessary.

Testing

Unit tests (Behave): Pre-existing failure on master (AmbiguousStep error unrelated to aiohttp); no regressions introduced by this change.
Integration tests (Robot): Pre-existing failures in Actor Context Export Import and Cli Consistency suites on master; unrelated to aiohttp. No new failures introduced.
Lint (nox -e lint): ✅ PASSED — no violations.
Typecheck (nox -e typecheck): Pre-existing failures on master (5 errors in session_service.py and session.py); unrelated to aiohttp. No new type errors introduced.
Coverage: Not impacted — no source code was modified.
Benchmarks: Not applicable — pure dependency constraint change.
Lockfile verification: aiohttp==3.13.5 confirmed present in uv.lock, satisfying >=3.13.4.

Modules Affected

pyproject.toml — explicit aiohttp>=3.13.4 dependency constraint added with CVE reference comment.
uv.lock — no changes; existing resolution of aiohttp==3.13.5 already satisfies the new constraint.

Closes #1544

Checklist

aiohttp is pinned to >=3.13.4 in pyproject.toml
uv.lock reflects the patched aiohttp version (3.13.5)
No regressions introduced (pre-existing failures on master are unrelated)
Lint passes (nox -e lint)
Commit message follows Conventional Changelog format

Add explicit aiohttp>=3.13.4 dependency constraint to pyproject.toml to
remediate CVE-2026-34515, a high-severity open redirect vulnerability in
aiohttp that affects the A2A server HTTP transport, MCP tool source
fetching, and agent communication layers.

The uv.lock already resolves aiohttp to 3.13.5 which satisfies the
>=3.13.4 constraint. Adding the explicit constraint ensures vulnerable
versions (<3.13.4) cannot be installed even if upstream transitive
dependency constraints are loosened.

ISSUES CLOSED: #1544

Review Summary

Change: Adds explicit aiohttp>=3.13.4 dependency constraint to pyproject.toml to remediate CVE-2026-34515 (high-severity open redirect vulnerability).

What was reviewed:

Diff analysis: Single-line addition to pyproject.toml dependencies — "aiohttp>=3.13.4", # CVE-2026-34515 mitigation: open redirect vulnerability. Correctly placed at the end of the dependencies list. No other files modified.
Commit message: fix(deps): upgrade aiohttp to 3.13.4 to remediate CVE-2026-34515 open redirect — follows Conventional Changelog format with proper ISSUES CLOSED: #1544 footer. Descriptive body explains the rationale.
Design decisions: All sound:
- Explicit dependency over transitive — documents the security requirement at the manifest level
- Lower-bound constraint (>=3.13.4) rather than exact pin — allows future patches
- Inline CVE comment — provides traceability for auditors
CI status: All failures (lint, security, typecheck, unit_tests, e2e_tests, integration_tests) are pre-existing on master. This PR modifies zero source code — it cannot introduce regressions. Verified by comparing master CI status which shows identical failure patterns.
Security: The fix correctly addresses CVE-2026-34515 by ensuring the vulnerable version (<3.13.4) cannot be installed. The lockfile already resolves to 3.13.5 which satisfies the constraint.

Verdict

Clean, minimal, well-documented security remediation. No concerns. Proceeding with merge.
