Security Tools, Identity & Access

openssl-encrypt versions before 1.4.9 contain a vulnerability where file passwords are not properly redacted in debug output. When passwords are supplied via bundled short-option spellings (e.g., -apHunter2) or abbreviated long-option spellings (e.g., --passw), the sanitizer fails to recognize and redact them. The sanitizer only handled exact option names, --option=value forms, and tokens starting with -p, leaving these alternate spellings unredacted. As a result, cleartext passwords are written to stderr and may appear in terminal scrollback, merged 2>&1 output, CI job logs, or GUI persistent debug logs. Anyone with access to these outputs can recover the plaintext password. Users should upgrade to openssl-encrypt 1.4.9 or later to remediate this information disclosure vulnerability.
