Metadata

  • Branch: fix/dependency-security-aiohttp-cve-2026-34515
  • Commit Message: fix(deps): upgrade aiohttp to 3.13.4 to remediate CVE-2026-34515 open redirect
  • Milestone: v3.8.0
  • Parent Epic: (orphan — no dependency-security Epic found; requires manual linking)

Vulnerability Details

  • Package: aiohttp
  • Vulnerable Version: 3.13.3
  • CVE ID: CVE-2026-34515
  • Fix Version: 3.13.4
  • Severity: High

Description

A vulnerability in aiohttp allows for an open redirect. 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). Any component that handles user-supplied URLs or redirect responses is potentially affected.

Recommendation

Upgrade aiohttp from 3.13.3 to 3.13.4 or later in pyproject.toml and regenerate the lockfile.

Subtasks

  • Update aiohttp version constraint in pyproject.toml to >=3.13.4
  • Run uv lock to regenerate uv.lock with the patched version (Note: uv.lock is gitignored in this project; uv lock confirms aiohttp resolves to 3.13.5)
  • Run nox -e lint and confirm no new lint violations
  • Run nox -e typecheck and confirm no new type errors
  • Run nox -e unit_tests and confirm all Behave scenarios pass
  • Run nox -e integration_tests and confirm all Robot Framework tests pass
  • Run nox -e coverage_report and confirm coverage remains ≥ 97%
  • Verify aiohttp==3.13.4 (or later) appears in the resolved lockfile (resolves to 3.13.5)

Definition of Done

  • aiohttp is pinned to >=3.13.4 in pyproject.toml
  • uv.lock reflects the patched aiohttp version (gitignored; confirmed via uv lock run)
  • No regressions introduced in any nox session
  • All nox stages pass
  • Coverage >= 97%

⚠️ Orphan Issue — Manual Linking Required

This issue could not be automatically linked to a parent Epic because no dependency-security Epic exists in the cleveragents/cleveragents-core repository.

Per CONTRIBUTING.md, all issues must be linked to a parent Epic. A project owner should either:

  1. Create a new Epic (e.g., EPIC: [dependency-security] Remediate vulnerable transitive and direct dependencies) and link this issue as a child (this issue blocks the Epic), or
  2. Link this issue to an existing security/infrastructure Epic if one is appropriate.

The correct dependency direction is:

Child issue #1544 BLOCKS parent Epic (the Epic cannot be closed until this issue is resolved).

Security Fix Implemented ✓

Pull Request: #1579 (combined fix for #1549 and #1544)

Changes

Added explicit aiohttp>=3.13.4 dependency to pyproject.toml to remediate CVE-2026-34513 and CVE-2026-34515.

Both CVEs are open redirect vulnerabilities that could allow attackers to redirect users to malicious sites for phishing attacks.

MoSCoW classification: MoSCoW/Must Have

Priority classification: Priority/High (confirmed)

Rationale: CVE-2026-34515 is a high-severity open redirect vulnerability in aiohttp affecting the same HTTP infrastructure as #1549. Both CVEs affect the A2A transport, MCP tool fetching, and agent protocol handlers. Security vulnerabilities in transport-layer dependencies are always Must Have — the platform cannot ship with known high-severity CVEs in its HTTP stack.

PR #1579 has been reviewed and changes requested. The pyproject.toml change is correct, but the PR is missing:

  1. uv.lock update — required by the Definition of Done
  2. Milestone assignment (should be v3.8.0)
  3. Type/Task label
  4. Dependency link (PR should block this issue)

Starting implementation on branch fix/dependency-security-aiohttp-cve-2026-34515.

Task: Upgrade aiohttp from 3.13.3 to >=3.13.4 to remediate CVE-2026-34515 (open redirect vulnerability).

Analysis: The uv.lock already resolves aiohttp to 3.13.5 (which satisfies >=3.13.4). The only change needed is to add an explicit aiohttp>=3.13.4 constraint to pyproject.toml to enforce the minimum version and document the security requirement.

Wave plan: Single wave — all subtasks are sequential (update pyproject.toml → regenerate lockfile → run nox validation sessions).

Implementation Status Update

Resume detected: This issue was previously partially implemented. PR #1579 already exists with the core fix.

Current State

PR #1579 (fix/dependency-security-aiohttp-cves) addresses both CVE-2026-34513 (#1549) and CVE-2026-34515 (#1544) by adding aiohttp>=3.13.4 to pyproject.toml.

PR Metadata Fixed

The following issues from the code review have been resolved:

  • Milestone set to v3.8.0
  • Label corrected: Type/BugType/Task
  • Dependency links added: issues #1544 and #1549 now depend on PR #1579

Regarding uv.lock

The uv.lock file is listed in .gitignore and is not tracked by git. Running uv lock locally confirms aiohttp resolves to 3.13.5 (satisfying >=3.13.4). The pyproject.toml constraint is the correct and sufficient mechanism for enforcing the security fix in this project.

PR Status

PR #1579 is open, mergeable, and ready for review. The code change is correct and complete.

PR #1579 Review Outcome: REQUEST_CHANGES (Redundant)

PR #1579 was reviewed and found to be blocked by a merge conflict and functionally redundant. The aiohttp>=3.13.4 dependency constraint that remediates CVE-2026-34515 is already present on master (line 50 of pyproject.toml, added by commit f0ff4bce which directly closed this issue).

PR #1579 attempted to address both #1549 and #1544 in a single commit, but since f0ff4bce was merged to master first, the PR now conflicts and has no remaining functional diff.

Note: This issue already has State/Completed label. The vulnerability is remediated on master.
