Description
Powerlevel10k before 1.20.19 contains an insecure temporary directory vulnerability in the bundled gitstatus/install script that reuses attacker-creatable directories when mktemp fails. Local attackers can pre-create the predictable gitstatus-install.tmp directory to replace the extracted gitstatusd binary, which then executes with the victim's privileges.
