Description

hermes is an implementation of the HERMES workflow to automatize software publication with rich metadata. From 0.8.1 to before 0.9.1, hermes subcommands take arbitrary options under the -O argument. These have been logged in raw form. If users provide sensitive data such as API tokens (e.g., via hermes deposit -O invenio_rdm.auth_token SECRET), these are written to the log file in plain text, making them available to whoever can access the log file. This vulnerability is fixed in 0.9.1.

Affected products

softwarepub hermes: from 0.8.1 before 0.9.1 — fixed in 0.9.1

How to fix

Upgrade to a fixed version: softwarepub hermes 0.9.1. Check the vendor advisory for mitigations.
