{"cve":"CVE-2022-24825","nvd":{"published":"2022-04-19T20:15:13.713","modified":"2026-06-17T04:32:36.247","status":"Modified","description":"Smokescreen is a simple HTTP proxy that fogs over naughty URLs. The primary use case for Smokescreen is to prevent server-side request forgery (SSRF) attacks in which external attackers leverage the behavior of applications to connect to or scan internal infrastructure. Smokescreen also offers an option to deny access to additional (e.g., external) URLs by way of a deny list. There was an issue in Smokescreen that made it possible to bypass the deny list feature by appending a dot to the end of user-supplied URLs, or by providing input in a different letter case. Recommended to upgrade Smokescreen to version 0.0.3 or later.","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-918"],"references":["https://github.com/stripe/smokescreen","https://github.com/stripe/smokescreen/security/advisories/GHSA-gcj7-j438-hjj2","https://github.com/stripe/smokescreen","https://github.com/stripe/smokescreen/security/advisories/GHSA-gcj7-j438-hjj2"],"products":["stripe:smokescreen"],"source":"nvd","synced_at":"2026-10-19T21:30:03.577988018+00:00"},"epss":{"cve":"CVE-2022-24825","score":0.0093,"percentile":0.60615,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gcj7-j438-hjj2","url":"https://osv.dev/vulnerability/GHSA-gcj7-j438-hjj2","summary":"Smokescreen SSRF via deny list bypass","modified":"2024-08-21T15:41:48.642826Z","packages":[{"ecosystem":"Go","name":"github.com/stripe/smokescreen","purl":"pkg:golang/github.com/stripe/smokescreen","ranges":["<0.0.3"],"fixed":["0.0.3"]}]},{"id":"GO-2022-0429","url":"https://osv.dev/vulnerability/GO-2022-0429","summary":"Smokescreen SSRF via deny list bypass in github.com/stripe/smokescreen","modified":"2026-03-03T04:48:58.449782Z","packages":[{"ecosystem":"Go","name":"github.com/stripe/smokescreen","purl":"pkg:golang/github.com/stripe/smokescreen","ranges":["<0.0.3"],"fixed":["0.0.3"]}]}],"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).
