However, if you specifically do not want them to be passed to subprocesses, you may use `env` argument in `subprocess` calls, like in this example:\n\n```\n\u003e\u003e\u003e subprocess.check_output([\"env\"], env={\"TEST\":\"1\"})\nb'TEST=1\\n'\n```\n\nIf you'd want to not pass any variables, you can set an empty dict:\n\n```\n\u003e\u003e\u003e subprocess.check_output([\"env\"], env={})\nb''\n```\n\nHowever, the bug in Sentry SDK \u003c2.8.0 causes **all environment variables** to be passed to the subprocesses when `env={}` is set, unless the Sentry SDK's [Stdlib](https://docs.sentry.io/platforms/python/integrations/default-integrations/#stdlib) integration is disabled. The Stdlib integration is enabled by default.\n\n### Patches\nThe issue has been patched in https://github.com/getsentry/sentry-python/pull/3251 and the fix released in [sentry-sdk==2.8.0](https://github.com/getsentry/sentry-python/releases/tag/2.8.0). The fix was also backported to [sentry-sdk==1.45.1](https://github.com/getsentry/sentry-python/releases/tag/1.45.1).\n\n### Workarounds\n\nWe strongly recommend upgrading to the latest SDK version. However, if it's not possible, and if passing environment variables to child processes poses a security risk for you, there are two options:\n\n1. In your application, replace `env={}` with the minimal dict `env={\"EMPTY_ENV\":\"1\"}` or similar.\n\nOR\n\n2. Disable Stdlib integration:\n```\nimport sentry_sdk\n\n# Should go before sentry_sdk.init\nsentry_sdk.integrations._DEFAULT_INTEGRATIONS.remove(\"sentry_sdk.integrations.stdlib.StdlibIntegration\")\n\nsentry_sdk.init(...)\n```\n\n### References\n* Sentry docs: [Default integrations](https://docs.sentry.io/platforms/python/integrations/default-integrations/)\n* Python docs: [subprocess module](https://docs.python.org/3/library/subprocess.html)\n* Patch https://github.com/getsentry/sentry-python/pull/3251","status":"published","published":"2024-07-18T17:18:46Z","modified":"2026-06-01T09:31:10Z","cvss":[{"version":"4.0","score":1.8,"vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N","level":"low"},{"version":"3.1","score":2.5,"vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:N/A:N","level":"low"}],"cwes":["CWE-200"],"updated_at":"2026-11-02T14:40:15.638885Z"}],"nvd":[{"id":"CVE-2024-40647","description":"sentry-sdk is the official Python SDK for Sentry.io.
