SCA: security update for changedetection.io (GHSA-jmrh-xmgh-x9j4)

critical Tenable Cloud Security Plugin ID 440027

Description

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

 - changedetection.io is a free open source web page change detection tool. Prior to 0.54.8, the
 @login_optionally_required decorator is placed before (outer to) @blueprint.route() instead of after it.
 In Flask, @route() must be the outermost decorator because it registers the function it receives. When the
 order is reversed, @route() registers the original undecorated function, and the auth wrapper is never in
 the call chain. This silently disables authentication on these routes. This vulnerability is fixed in
 0.54.8. (CVE-2026-35490)

Solution

Update the changedetection.io library and its related packages to version 0.54.8 or later.
