{"id":"CVE-2026-41895","summary":"changedetection.io: XXE vulnerability in the changedetection.io project","details":"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(...).","aliases":["GHSA-v7cp-2cx9-x793","PYSEC-2026-29"],"modified":"2026-07-08T08:13:13.218370380Z","published":"2026-05-12T16:52:23.680Z","database_specific":{"cwe_ids":["CWE-611"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41895.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41895.json"},{"type":"ADVISORY","url":"https://github.com/dgtlmoon/changedetection.io/security/advisories/GHSA-v7cp-2cx9-x793"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41895"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dgtlmoon/changedetection.io","events":[{"introduced":"0"},{"last_affected":"9f3a9fdc18bba404244801e5df8109e213ce9ff4"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:webtechnologies:changedetection:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"0.54.9"}]}}],"versions":["0.54.9","0.54.8","0.54.7","0.54.6","0.54.5","0.54.4","0.54.3","0.54.2","0.54.1","0.53.7","0.53.6","0.53.5","0.53.4","0.53.3","0.53.2","0.53.1","0.52.9","0.52.8","0.52.7","0.52.5","0.52.4","0.52.3","0.52.2","0.52.1","0.51.4","0.51.3","0.51.2","0.51.1","0.51.01","0.51.00","0.50.43","0.50.42","0.50.41","0.50.40","0.50.39","0.50.38","0.50.37","0.50.35","0.50.34","0.50.33","0.50.32","0.50.31","0.50.30","0.50.29","0.50.28","0.50.27","0.50.26","0.50.25","0.50.24","0.50.23","0.50.22","0.50.21","0.50.20","0.50.19","0.50.18","0.50.17","0.50.16","0.50.15","0.50.14","0.50.13","0.50.12","0.50.11","0.50.10","0.50.9","0.50.8","0.50.7","0.50.6","0.50.5","0.50.4","0.50.3","0.50.2","0.50.1","0.50.01","0.49.18","0.49.17","0.49.16","0.49.15","0.49.14","0.49.13","0.49.12","0.49.11","0.49.10","0.49.9","0.49.8","0.49.7","0.49.6","0.49.5","0.49.4","0.49.3","0.49.2","0.49.1","0.49.0","0.48.06","0.48.05","0.48.04","0.48.03","0.48.01","0.48.00","0.47.06","0.47.05","0.47.04","0.47.03","0.47.01","0.47.00","0.46.04","0.46.03","0.46.02","0.46.01","0.46.00","0.45.26","0.45.25","0.45.24","0.45.23","0.45.22","0.45.21","0.45.20","0.45.19","0.45.18","0.45.17","0.45.16","0.45.15","0.45.14","0.45.13","0.45.12","0.45.10","0.45.9","0.45.8.1","0.45.8","0.45.7.3","0.45.7.2","0.45.7.1","0.45.7","0.45.6","0.45.5","0.45.4","0.45.3","0.45.2","0.45.1","0.45","0.44.2","0.44.1","0.44","0.43.2","0.43.1","0.43","0.42.3","0.42.2","0.42.1","0.42","0.41.1","0.41","0.40.3","0.40.2","0.40.1.1","0.40.1.0","0.40.0.4","0.40.0.3","0.40.0.2","0.40.0","0.39.22.1","0.39.22","0.39.21.1","0.39.21","0.39.20.4","0.39.20.3","0.39.20.2","0.39.20.1","0.39.20","0.39.19.1","0.39.19","0.39.18","0.39.17.2","0.39.17.1","0.39.17","0.39.16","0.39.15","0.39.14","0.39.13.1","0.39.13","0.39.12","0.39.11","0.39.10","0.39.9","0.39.8","0.39.7","0.39.6","0.39.5","0.39.4","0.39.3","0.39.2","0.39.1","0.39","0.38.2","0.38.1","0.38","0.37","0.35","0.34","0.33","0.32","0.31","0.30","0.29","0.28","0.27","0.26","0.25","0.24","0.23","0.22","0.21","0.2","0.12","0.11","0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41895.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
