{"cve":"CVE-2026-29039","nvd":{"published":"2026-03-06T07:16:01.573","modified":"2026-06-17T10:29:29.457","status":"Analyzed","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:P","score":8.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-94"],"references":["https://github.com/dgtlmoon/changedetection.io/commit/417d57e5749441e4be9acc4010369bded805d66f","https://github.com/dgtlmoon/changedetection.io/releases/tag/0.54.4","https://github.com/dgtlmoon/changedetection.io/security/advisories/GHSA-6fmw-82m7-jq6p"],"products":["webtechnologies:changedetection"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-29039","score":0.00538,"percentile":0.45341,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-6fmw-82m7-jq6p","url":"https://osv.dev/vulnerability/GHSA-6fmw-82m7-jq6p","summary":"changedetection.io vulnerable to XPath - Arbitrary File Read via unparsed-text()","modified":"2026-07-13T07:26:51.624805782Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.54.4"],"fixed":["0.54.4"]}]},{"id":"PYSEC-2026-2128","url":"https://osv.dev/vulnerability/PYSEC-2026-2128","summary":"","modified":"2026-07-13T07:15:17.111794953Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.54.4"],"fixed":["0.54.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
