Overview

changedetection.io is a Website change detection and monitoring service

Affected versions of this package are vulnerable to Arbitrary Code Injection via the unparsed-text function in XPath expressions processed by the application. An attacker can access and read arbitrary files from the server's filesystem by supplying crafted input to the include_filters field, which is not properly sanitized to block dangerous functions.
