Vulnerability in openssl_encrypt (CVE-2026-81715)
Summary
Vulnerability in openssl_encrypt (CVE-2026-81715). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 1.4.9 or later.
Original description
The description as published by the source.
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.
