{"cve":"CVE-2024-32651","nvd":{"published":"2024-04-26T00:15:08.550","modified":"2026-06-17T07:30:09.590","status":"Deferred","description":"changedetection.io is an open source web page change detection, website watcher, restock monitor and notification service. There is a Server Side Template Injection (SSTI) in Jinja2 that allows Remote Command Execution on the server host. Attackers can run any system command without any restriction and they could use a reverse shell. The impact is critical as the attacker can completely takeover the server machine. This can be reduced if changedetection is behind a login page, but this isn't required by the application (not by default and not enforced).","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:H/A:H","score":10.0},"cwes":["CWE-1336"],"references":["https://blog.hacktivesecurity.com/index.php/2024/05/08/cve-2024-32651-server-side-template-injection-changedetection-io/","https://github.com/dgtlmoon/changedetection.io/releases/tag/0.45.21","https://github.com/dgtlmoon/changedetection.io/security/advisories/GHSA-4r7v-whpg-8rx3","https://www.onsecurity.io/blog/server-side-template-injection-with-jinja2","https://blog.hacktivesecurity.com/index.php/2024/05/08/cve-2024-32651-server-side-template-injection-changedetection-io/"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-32651","score":0.83601,"percentile":0.99687,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4r7v-whpg-8rx3","url":"https://osv.dev/vulnerability/GHSA-4r7v-whpg-8rx3","summary":"changedetection.io has a Server Side Template Injection using Jinja2 which allows Remote Command Execution","modified":"2026-10-27T16:30:06.791869101Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.45.21"],"fixed":["0.45.21"]}]},{"id":"PYSEC-2026-310","url":"https://osv.dev/vulnerability/PYSEC-2026-310","summary":"changedetection.io has a Server Side Template Injection using Jinja2 which allows Remote Command Execution","modified":"2026-07-13T16:15:10.494328181Z","packages":[{"ecosystem":"PyPI","name":"changedetection-io","purl":"pkg:pypi/changedetection-io","ranges":["<0.45.21"],"fixed":["0.45.21"]}]}],"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).
