{"id":"CVE-2026-50187","summary":"Oh My Zsh: Arbitrary Code Execution in oh-my-zsh dotenv plugin via malicious .env files","details":"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.","aliases":["GHSA-3rgh-p3mg-rjqg"],"modified":"2026-08-20T03:54:25.306707860Z","published":"2026-08-18T15:09:51.956Z","database_specific":{"cwe_ids":["CWE-94"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50187.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"2026-05-28"}]}],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50187.json"},{"type":"ADVISORY","url":"https://github.com/ohmyzsh/ohmyzsh/security/advisories/GHSA-3rgh-p3mg-rjqg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50187"},{"type":"FIX","url":"https://github.com/ohmyzsh/ohmyzsh/commit/d170d18746bb06db7b2fc97b67e281597a3fc152"},{"type":"FIX","url":"https://github.com/ohmyzsh/ohmyzsh/pull/13778"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ohmyzsh/ohmyzsh","events":[{"introduced":"0"},{"fixed":"d170d18746bb06db7b2fc97b67e281597a3fc152"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50187.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
