CVE-2026-110102: Powerlevel10k insecure download in gitstatus installation script

CVE-2026-110102 · Severity: high · CVSS 7.5 · Published 2026-10-13

Powerlevel10k is a theme for the Zsh shell used to customize terminal appearance. Versions through 1.20.0 install a daemon called gitstatusd via a script that does not verify the authenticity of downloaded files. An attacker on the network can intercept the download, replace it with malicious code, and gain execution as the user every time the shell prompt is displayed.

Technologies: Romkatv Powerlevel10k. Vendors: Romkatv.

Technical details

The gitstatus/install script uses curl -k to disable TLS certificate verification and fails to validate SHA-256 checksums if no checksum utility is available on the system. This allows network-positioned attackers to perform man-in-the-middle attacks on downloads from github.com, substitute a malicious archive, and achieve arbitrary code execution as the gitstatusd daemon under the user's privileges on every prompt.
