SCA: security update for changedetection.io (GHSA-3c45-4pj5-ch7m)

high Tenable Cloud Security Plugin ID 438022

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. In versions prior to 0.54.1,
 changedetection.io is vulnerable to Server-Side Request Forgery (SSRF) because the URL validation function
 `is_safe_valid_url()` does not validate the resolved IP address of watch URLs against private, loopback,
 or link-local address ranges. An authenticated user (or any user when no password is configured, which is
 the default) can add a watch for internal network URLs. The application fetches these URLs server-side,
 stores the response content, and makes it viewable through the web UI — enabling full data exfiltration
 from internal services. Version 0.54.1 contains a fix for the issue. (CVE-2026-27696)
