SCA: security update for changedetection.io (GHSA-6fmw-82m7-jq6p)

critical Tenable Cloud Security Plugin ID 438346

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 version 0.54.4, the
 changedetection.io application allows users to specify XPath expressions as content filters via the
 include_filters field. These XPath expressions are processed using the elementpath library which
 implements XPath 3.0/3.1 specification. XPath 3.0 includes the unparsed-text() function which can read
 arbitrary files from the filesystem. The application does not validate or sanitize XPath expressions to
 block dangerous functions, allowing an attacker to read any file accessible to the application process.
 This issue has been patched in version 0.54.4. (CVE-2026-29039)
