Caveat verdict
fastgithub
GitHub access accelerator that sets up a local proxy server (loopback 127.0.0.1:38457) and writes shell config; all operations are local and the file_write/credential_store capabilities are used only for standard proxy configuration as documented.
โ Flagged for review โ coarse, uncorroborated signal, not a confirmed exploit. Review the config yourself before installing.
Automated static analysis โ not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
