Description

Summary

Passwords passed via the --password / -p CLI argument in openssl_encrypt/modules/crypt_cli_subparser.py at lines 150-154 are visible to any user on the system via ps aux or /proc/[pid]/cmdline.

Affected Code

subparser.add_argument(
    "--password", "-p",
    help="Password (will prompt if not provided, or use CRYPT_PASSWORD environment variable)",
)

Similarly, --keystore-password exposes the keystore password.

Impact

On multi-user systems, any user can observe the encryption password by listing processes. The CRYPT_PASSWORD environment variable alternative is also visible via /proc/[pid]/environ (though with slightly restricted access).

Recommended Fix

  • Document the security implications prominently
  • Recommend interactive prompting (already supported) as the secure default
  • Consider supporting password file descriptors (--password-fd) or reading from stdin
  • Consider marking the argument as deprecated in favor of interactive prompting

Fix

Fixed in commit e78a366 on branch releases/1.4.x — added --password-file and --password-fd arguments; added OPENSSL_ENCRYPT_PASSWORD env var support; --password now emits deprecation warning.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openssl-encrypt. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update openssl-encrypt to 1.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h3m5-p59h-x88p is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-h3m5-p59h-x88p is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-h3m5-p59h-x88p. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Is GHSA-h3m5-p59h-x88p in your dependencies?

O3 detects GHSA-h3m5-p59h-x88p across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
