Sending a private key in a GET query also exposes it to URL logging infrastructure. - **Trigger:** A consumer calls a supported gasless contract transaction or obtains an ERC-20 payment quote with a private-key-backed signer. - **Impact:** The gateway and intermediaries that log request URLs can obtain the wallet private key and control its assets. - **Evidence paths:** dist/contract/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T11:25:23.977Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Private-key extraction and transmission to a remote sponsorship gateway. - **Rationale:** The package has a severe runtime private-key disclosure flaw. Static source does not establish install-time abuse or intent to conduct unrelated malicious activity, so it should be warned rather than blocked as malware. - **Files touched:** dist/contract/index.js - **Network endpoints:** gateway.verified.network ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for:** Gasless contract calls extract the private key from the supplied signer., The extracted key is sent to the vendor gateway in sponsorship requests, including a URL query parameter., The key transmission occurs during ordinary SDK transaction and quote operations, not only a separately named export. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The network target is a fixed package-owned sponsorship gateway, and the source is not obfuscated. ## Public findings ### 1.
