# HTTPApproval dashboard renders tool arguments as raw HTML, allowing approval-page XSS to approve dangerous tools ## Summary `praisonai.bots.HTTPApproval` renders pending tool approval arguments directly into the approval dashboard HTML. An attacker-controlled tool argument can inject JavaScript into that page. When a human opens the approval URL to inspect the risky tool request, the script runs in the dashboard origin and can POST to the same request's `/approve/{request_id}/decide` endpoint, causing `HTTPApproval` to return `approved=True`. The local PoV uses a harmless `touch /tmp/prai010 #` command prefix and stops at the approval decision. It does not execute the command. ## Affected Versions Proposed affected range: `>= 4.5.2, <= 4.6.57`. Validated affected: - current head `2f9677abb2ea68eab864ee8b6a828fd0141612e1` (`v4.6.57-4-g2f9677ab`) - `v4.5.2` - `v4.5.3` - `v4.5.124` - `v4.5.126` - `v4.5.128` - `v4.6.10` - `v4.6.56` - `v4.6.57` `v4.5.0` and `v4.5.1` do not contain the HTTPApproval backend. ## Impact An attacker who can influence an agent task or prompt enough to produce a dangerous tool call can embed a short XSS payload in the tool argument. When the human approver opens the HTTP approval page, the script can approve the pending dangerous tool call before the human explicitly clicks Approve or Deny. This bypasses the human-in-the-loop approval boundary for dangerous tools such as `execute_command`, `execute_code`, `delete_file`, or other tools gated through `HTTPApproval`. If the agent continues after approval, the dangerous tool runs with the privileges of the PraisonAI process. ## Why This Is Not Intended Behavior PraisonAI documentation describes approval as a safety control that pauses an agent before risky tools and asks a human or configured channel to allow or deny execution. The documentation also lists `http` as a supported non-console approval backend. Opening the approval page to inspect a risky command should not itself app
