No problems traced to this repository code in these checks; a short run cannot prove safety. 48 listed items (named-host connections, static matches, dependency advisories) are below and do not change this verdict. 2 static matches retained as context.
Gitleaks found a possible hardcoded secret; value withheld. 7 distinct locations. 19 findings.
OSV reports a known vulnerability in this dependency version. golang.org/x/net 5 findings.
Reviewed as expected for a test run: attempted writes that failed, so nothing was written.
