{"cve":"CVE-2024-51998","nvd":{"published":"2024-11-08T00:15:15.490","modified":"2026-06-17T08:06:46.520","status":"Deferred","description":"changedetection.io is a free open source web page change detection tool. The validation for the file URI scheme falls short, and results in an attacker being able to read any file on the system. This issue only affects instances with a webdriver enabled, and `ALLOW_FILE_URI` false or not defined. The check used for URL protocol, `is_safe_url`, allows `file:` as a URL scheme. It later checks if local files are permitted, but one of the preconditions for the check is that the URL starts with `file://`. The issue comes with the fact that the file URI scheme is not required to have double slashes. This issue has been addressed in version 0.47.06 and all users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6},"cwes":["CWE-22"],"references":["https://github.com/dgtlmoon/changedetection.io/blob/e0abf0b50507a8a3d0c1d8522ab23519b3e4cdf4/changedetectionio/model/Watch.py#L11-L13","https://github.com/dgtlmoon/changedetection.io/commit/49bc982c697169c98b79698889fb9d26f6b3317f","https://github.com/dgtlmoon/changedetection.io/security/advisories/GHSA-6jrf-rcjf-245r"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:57:07.693694550+00:00"},"epss":{"cve":"CVE-2024-51998","score":0.00688,"percentile":0.5275,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6jrf-rcjf-245r","url":"https://osv.dev/vulnerability/GHSA-6jrf-rcjf-245r","summary":"changedetection.io path traversal using file URI scheme without supplying hostname","modified":"2026-07-07T17:56:52.726492494Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.47.6"],"fixed":["0.47.6"]}]},{"id":"PYSEC-2026-1239","url":"https://osv.dev/vulnerability/PYSEC-2026-1239","summary":"changedetection.io path traversal using file URI scheme without supplying hostname","modified":"2026-07-07T17:47:24.574643872Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.47.6"],"fixed":["0.47.6"]}]}],"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).
