GHSA-v7cp-2cx9-x793
PYSEC-2026-29
Summary changedetection.io is a free open source web page change detection tool. In 0.54.9 and earlier, xpath_filter() switches to XML mode for XML/RSS content and creates etree.XMLParser(strip_cdata=False) without explicitly disabling external entity resolution, external DTD loading, or network-backed entity lookup. The helper then parses untrusted XML bytes directly with etree.fromstring(...).
