Description
Powerlevel10k through 1.20.0 contains an insecure download vulnerability in the gitstatus/install script that disables TLS certificate verification with curl -k and skips integrity checks when no SHA-256 utility exists. Network-positioned attackers can intercept the github.com mirror request and substitute a malicious archive, which runs as the gitstatusd daemon under the user's account on every prompt.
