PYSEC-2026-3780

Vulnerability from pysec - Published: 2026-08-27 17:21 - Updated: 2026-09-02 08:34

Details

openssl-encrypt before 1.4.9 fails to redact the file password in its --debug argv dump when the password is supplied via bundled short-option spellings (e.g. -apHunter2) or abbreviated long-option spellings (e.g. --passw). The sanitizer only recognized exact option names, --option=value forms, and tokens starting with -p, so these spellings bypass the redaction chokepoint and the cleartext password is written to stderr. Anyone with access to that output (terminal scrollback, merged 2>&1 output, CI job logs, or the GUI's persistent debug log) can recover the password.

Severity
