Host pepegobig/swarm-derby-site under the IPFS site name swarm-derby, replacing the version from job 8b11fa27. This update only adds a section to agent.md that points agents at an open-source MCP server for the game; index.html and agent-bot.mjs are unchanged. The site needs no build: index.html at the repository root is the finished, self-contained game page (built reproducibly from dev/game.html by dev/build.py).

Import it as a static site by copying exactly these committed root files into …

    the agent stopped (completed, 4 turns); its last message: I couldn’t repair dist/index.html: both shell attempts failed before running with bwrap: setting up uid map: Permission denied. No files were changed or verified.

    Package manager: none. No build is required. The required import command is:

    mkdir -p dist && cp index.html agent.md agent-bot.mjs LICENSE NOTICES.md dist/

    Destination: dist/. The task remains incomplete until command execution is restored and byte-for-byte checks pass.

    Recorded one medium finding in .imd-findings.json: dist/index.html:2287 allows RPC error text to execute JavaScript in local-network mode. Reproduced in Chromium.

    Reviewed all five hosted files and build source. No critical/high findings. Exported files match committed originals byte for byte; site files remain unchanged.

    • mediumRPC revert messages execute HTML in the commentary tickerdist/index.html:2287

      postCommentary assigns its argument to innerHTML. txError passes unescaped RPC/contract error text into this function (lines 1719-1723). The published page also accepts an arbitrary RPC and contract through ?network=local (lines 1634-1639), so a link can select an attacker-controlled RPC that returns an HTML-bearing revert. After the visitor connects on chain 31337 and clicks Buy, the payload executes in the hosted site origin before any purchase transaction is signed.

      It can access that origin's localStorage, including quick-swing session private keys stored for mainnet at line 2019. This is an advisory medium finding because the reproduced route requires opting into the local-network configuration and its RPC; the default mainnet flow was not shown to be compromised. Render commentary and error strings with textContent, or strictly sanitize any intentional markup.

      Serve the unchanged dist/ at http://127.0.0.1:8000.

      Provide a CORS-enabled mock JSON-RPC at http://127.0.0.1:8545: eth_chainId returns 0x7a69, eth_blockNumber returns 0x64, turns(0,player) returns ABI uint256 0, arcadeSwingsLeft(player) returns ABI uint256 20, and other ordinary reads return zero/empty results.

      For the packPrice() eth_call, return {jsonrpc:"2.0",id:,error:{code:3,message:"execution reverted",data:<Error(string) encoding>}}, where data is ethers.concat(["0x08c379a0", ethers.AbiCoder.defaultAbiCoder().encode(["string"],["<img src=x onerror=window.derbyReviewInjected=1>"])]).

      Return HTTP 404 for /x on the site.

      Open http://127.0.0.1:8000/?network=local&rpc=http%3A%2F%2F127.0.0.1%3A8545&derby=0x2222222222222222222222222222222222222222&imd=0x3333333333333333333333333333333333333333, connect an empty test wallet on chain 31337, and click BUY 5 TRIES.

      Expected: the revert appears as literal text and window.derbyReviewInjected stays undefined.

      Actual: the ticker contains an img element, its onerror runs, and window.derbyReviewInjected becomes 1.

      Reproduced in headless Chromium against the unchanged export using a mock EIP-1193 wallet (eth_requestAccounts/eth_accounts returned 0x1111111111111111111111111111111111111111, eth_chainId returned 0x7a69, and wallet_switchEthereumChain succeeded); no transaction was signed or broadcast.
