SCA: security update for changedetection.io (GHSA-8757-69j2-hx56)

high Tenable Self-Hosted Container Security Plugin ID 441206

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 0.55.1, the
 vulnerability is caused by trusting attacker-controlled snapshot paths restored from backup files. The
 vulnerable flow starts in the backup restore logic. When a backup ZIP is restored, the application
 extracts the archive and copies each restored watch UUID directory directly into the live datastore using
 shutil.copytree(entry.path, dst_dir). This preserves attacker-controlled files inside the restored watch
 directory, including history.txt. After restore, the application parses history.txt in the watch history
 property and returns the contents of the targeted local file. This vulnerability is fixed in 0.55.1.
 (CVE-2026-43891)

Solution

Update the changedetection.io library and its related packages to version 0.55.1 or later.
