CVE-2026-22798

Secret disclosure via raw option logging

Published Jan 12, 2026 · Updated Jan 12, 2026

Sensitive-data exposure in softwarepub hermes 0.8.1 through 0.9.0 allows local users to read secrets from accessible log files. The CLI main entry point passes the complete argparse namespace to a debug logger, leaving values supplied through -O unmasked in hermes.log. Exposure requires secret-bearing -O input and access to the resulting local or CI log, limiting the consequence to disclosure of logged option values.
