medium Tenable Cloud Security Plugin ID 440362

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Decidim is a participatory democracy framework. Starting in version 0.19.0 and prior to versions 0.30.5
 and 0.31.1, a vulnerability allows any registered and authenticated user to accept or reject any
 amendments. The impact is on any users who have created proposals where the amendments feature is enabled.
 This also elevates the user accepting the amendment as the author of the original proposal as people
 amending proposals are provided coauthorship on the coauthorable resources. Versions 0.30.5 and 0.31.1 fix
 the issue. As a workaround, disable amendment reactions for the amendable component (e.g. proposals).
