Quick fix

PYSEC-2026-3964 — openssl-encrypt: upgrade to the fixed version with the command below.

pip install --upgrade 'openssl-encrypt>=1.4.9'

Details

openssl_encrypt (pip package openssl-encrypt) versions <= 1.4.8 do not redact the keyserver bearer token passed as the positional argument to 'keyserver set-token' in the --debug argv dump, because sanitize_argv_for_debug fails to sanitize it. As a result the token is printed in cleartext to stderr under --debug (even without --unsafe-show-secrets), persisting the credential in logs and terminal history. Fixed in 1.4.9.
