CVE-2018-25083Public exploitNetwork attack vector

Command execution via shell-interpolated branch name

Published Mar 27, 2023 · Updated Feb 24, 2025

Command injection in pullit before 1.4.0 allows remote attackers to execute arbitrary commands via a crafted GitHub branch name. The fetch method interpolates a pull request's unvalidated head.ref value into an execSync shell command that runs git fetch and git checkout. Execution requires a local user to run pullit and select the attacker's pull request, after which commands run with that user's privileges.
