{"cve":"CVE-2024-56509","nvd":{"published":"2024-12-27T16:15:25.333","modified":"2026-06-17T08:12:16.110","status":"Deferred","description":"changedetection.io is a free open source web page change detection, website watcher, restock monitor and notification service. Improper input validation in the application can allow attackers to perform local file read (LFR) or path traversal attacks. These vulnerabilities occur when user input is used to construct file paths without adequate sanitization or validation. For example, using file:../../../etc/passwd or file: ///etc/passwd can bypass weak validations and allow unauthorized access to sensitive files. Even though this has been addressed in previous patch, it is still insufficient. This vulnerability is fixed in 0.48.05.","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","CWE-200"],"references":["https://github.com/dgtlmoon/changedetection.io/commit/f7e9846c9b40a229813d19cdb66bf60fbe5e6a2a","https://github.com/dgtlmoon/changedetection.io/security/advisories/GHSA-j5vv-6wjg-cfr8","https://github.com/dgtlmoon/changedetection.io/security/advisories/GHSA-j5vv-6wjg-cfr8"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:57:56.913276502+00:00"},"epss":{"cve":"CVE-2024-56509","score":0.00715,"percentile":0.53745,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j5vv-6wjg-cfr8","url":"https://osv.dev/vulnerability/GHSA-j5vv-6wjg-cfr8","summary":"changedetection.io Vulnerable to Improper Input Validation Leading to LFR/Path Traversal","modified":"2026-09-10T03:50:21.630420297Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.48.05"],"fixed":["0.48.05"]}]},{"id":"PYSEC-2026-1242","url":"https://osv.dev/vulnerability/PYSEC-2026-1242","summary":"changedetection.io Vulnerable to Improper Input Validation Leading to LFR/Path Traversal","modified":"2026-07-07T17:47:26.890146780Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.48.05"],"fixed":["0.48.05"]}]}],"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).
