Severity: Medium

Description

tool_check_task_status in workspace/a2a_tools_delegation.py (staging) does NOT sanitize summary and response_preview fields before returning delegation results via the JSON polling endpoint.

Affected files

workspace/a2a_tools_delegation.py (staging branch)

Details

  • Matching-by-id path (task_id filter): d["summary"] and d["response_preview"] returned raw — no sanitize_a2a_result call.
  • Bulk-list path: same — raw summary and response_preview fields embedded in JSON response.

Root cause

Staging's tool_check_task_status was never wired with sanitize_a2a_result. Main's version (PR #433, commit c2048f5d) has the correct sanitization. Staging has a parallel implementation that is missing this fix.

Second architectural issue

Staging's _sanitize_a2a.py uses ZWSP (U+200B) approach. Main uses space-substitution ([/ A2A_RESULT_FROM_PEER]). Per CEO decision (Option 1: space-substitution), staging needs rebase to main's approach before staging→main merge. Merging staging as-is would replace main's _sanitize_a2a.py with the ZWSP version.

Fix

  1. Wire sanitize_a2a_result into tool_check_task_status matching the main pattern (already present in read_delegation_results and tool_delegate_task on staging).
  2. Rebase staging's _sanitize_a2a.py to use main's space-substitution approach.

Status

Confirmed by diff analysis during audit #17 (2026-05-11).

[triage-agent] CLOSING — false claim. Verified: staging HEAD has OFFSEC-003 sanitization intact (lines 418-419 and 430-431 of a2a_tools_delegation.py). The import from _sanitize_a2a import sanitize_a2a_result is present. Issue #413 covers the same finding and is closed. This is a duplicate that mischaracterized the staging state.
