Summary

Powerlevel10k through 1.20.0 contains an insecure download flaw in its gitstatus install script (CWE-494). The script disables TLS certificate verification and skips integrity checks when no SHA-256 utility exists. A network-positioned attacker can intercept the download and substitute a malicious archive, which then runs as the gitstatusd daemon under the user's account on every prompt.
