SCA: security update for tendenci (GHSA-339m-4qw5-j2g3)

medium Tenable Cloud Security Plugin ID 436863

Description

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

 - Tendenci is an open source content management system built for non-profits, associations and cause-based
 sites. Versions 15.3.11 and below include a critical deserialization vulnerability in the Helpdesk module
 (which is not enabled by default). This vulnerability allows Remote Code Execution (RCE) by an
 authenticated user with staff security level due to using Python's pickle module in helpdesk /reports/.
 The original CVE-2020-14942 was incompletely patched. While ticket_list() was fixed to use safe JSON
 deserialization, the run_report() function still uses unsafe pickle.loads(). The impact is limited to the
 permissions of the user running the application, typically www-data, which generally lacks write (except
 for upload directories) and execute permissions. This issue has been fixed in version 15.3.12.
 (CVE-2026-23946)
