Doc Text:
A flaw was found in the `dotenv` plugin of Oh My Zsh. A remote attacker could craft a malicious `.env` file containing arbitrary shell commands. When a user changes into a directory containing this file, the `dotenv` plugin processes it, leading to the execution of these commands with the user's privileges. This vulnerability allows for arbitrary code execution.

Description OSIDB Bzimport 2026-08-18 15:25:55 UTC
Oh My Zsh is a community-driven framework for managing Zsh configuration. Prior to 2026-05-28, the dotenv plugin in plugins/dotenv/dotenv.plugin.zsh passes ZSH_DOTENV_FILE to source after a directory change into a folder containing a .env file, allowing syntactically valid shell commands in the file to execute with the current account's privileges, including without a prompt when ZSH_DOTENV_PROMPT=false or after the default prompt accepts an empty Enter response. This issue is fixed in versions released after 2026-05-28.
