CVE-2026-56840
Published:July 20, 2026
Updated:August 27, 2026
"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.
