Summary

Closes #1549 by adding an explicit aiohttp>=3.13.4 dependency to pyproject.toml to remediate a high-severity open redirect vulnerability (CVE-2026-34513).

Vulnerability Addressed

CVE-2026-34513

  • Package: aiohttp
  • Vulnerable Version: 3.13.3
  • Fix Version: 3.13.4
  • Severity: High
  • Impact: Open redirect allowing attackers to craft malicious URLs that redirect users to arbitrary external sites, enabling phishing attacks or security control bypass

Changes Made

pyproject.toml: Added explicit dependency aiohttp>=3.13.4 to the project dependencies list.

While aiohttp is currently a transitive dependency (via langchain-community and uvicorn), adding it as an explicit dependency with a minimum version constraint ensures:

  1. Vulnerable versions (<3.13.4) cannot be installed
  2. The fix is enforced even if upstream dependencies have loose version constraints
  3. The security requirement is documented in project dependencies

Affected Components

The CleverAgents platform uses aiohttp as part of its async HTTP infrastructure:

  • A2A server communication (HTTP transport)
  • Tool source fetching (MCP servers, Agent Skills)
  • Agent-to-agent protocol handlers

Verification

  • uv lock resolves aiohttp==3.13.5 (satisfies >=3.13.4 constraint) ✅
  • nox -e lint — pre-existing failure on master (unrelated to this change) ⚠️
  • nox -e typecheck — pre-existing failures on master (5 errors in session_service.py and session.py, unrelated to this change) ⚠️
  • nox -e security_scan — pre-existing vulture failure on master (unused variables in extension_protocols.py, unrelated to this change) ⚠️
  • nox -e unit_tests — pre-existing failure on master (unrelated to this change) ⚠️

Note: All CI failures are pre-existing on the master branch and are NOT introduced by this change. This can be verified by comparing CI status on master HEAD (0382b2f7) which shows the same failures.

Add explicit aiohttp>=3.13.4 dependency to pyproject.toml to remediate
CVE-2026-34513, a high-severity open redirect vulnerability in aiohttp.

An attacker could craft a malicious URL that, when processed by the
application, redirects users to an arbitrary external site. This can be
exploited for phishing attacks or to bypass security controls.

The CleverAgents platform uses aiohttp as part of its async HTTP
infrastructure (A2A server, tool source fetching, and agent communication
layers). Adding an explicit minimum version constraint ensures the
vulnerable version (3.13.3) cannot be installed even as a transitive
dependency.

⚠️ Merge Retry — Closing as Already Applied

Attempt 2 merge retry result: CONFLICT — change already on master.

Investigation findings:

  • The PR's change (aiohttp>=3.13.4 added to pyproject.toml dependencies) is already present on master at line 50
  • Master has: "aiohttp>=3.13.4", # CVE-2026-34515 mitigation: open redirect vulnerability
  • PR has: "aiohttp>=3.13.4", # Security: CVE-2026-34513 open redirect mitigation
  • The substantive dependency constraint is identical — only the CVE number in the comment differs slightly
  • This creates a merge conflict because both branches modified the same area of pyproject.toml
  • mergeable: false was correctly reported by Forgejo
  • The merge API returned success but the rebase could not actually be applied (silent failure)

Resolution: Closing this PR as the intended change has already been incorporated into master. The linked issue #1549 should already be resolved.
