{"cve":"CVE-2026-25527","nvd":{"published":"2026-02-19T15:16:11.947","modified":"2026-06-17T10:24:47.783","status":"Analyzed","description":"changedetection.io is a free open source web page change detection tool. In versions prior to 0.53.2, the `/static/<group>/<filename>` route accepts `group=\"..\"`, which causes `send_from_directory(\"static/..\", filename)` to execute. This moves the base directory up to `/app/changedetectionio`, enabling unauthenticated local file read of application source files (e.g., `flask_app.py`). Version 0.53.2 fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-22"],"references":["https://github.com/dgtlmoon/changedetection.io/commit/9d38b4517364831889b5b0d7b3465fd060403fd4","https://github.com/dgtlmoon/changedetection.io/security/advisories/GHSA-9jj8-v89v-xjvw"],"products":["webtechnologies:changedetection"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-25527","score":0.01025,"percentile":0.63598,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9jj8-v89v-xjvw","url":"https://osv.dev/vulnerability/GHSA-9jj8-v89v-xjvw","summary":"changedetection.io is vulnerable to unauthenticated static path traversal","modified":"2026-07-20T19:15:27.590444750Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.53.2"],"fixed":["0.53.2"]}]},{"id":"PYSEC-2026-2124","url":"https://osv.dev/vulnerability/PYSEC-2026-2124","summary":"","modified":"2026-07-13T07:15:16.972888298Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.53.2"],"fixed":["0.53.2"]}]}],"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).
