An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-29188 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/stripe/smokescreen (Go): affected all versions; fixed in 0.0.4\n- github.com/stripe/smokescreen (Go): affected all versions; fixed in 0.0.4\n- github.com/stripe/smokescreen (Go): affected all versions; fixed in 0.0.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-29188/ (Markdown: https://insights.sbomify.com/CVE-2022-29188/index.md)","id":"CVE-2022-29188","markdown":"https://insights.sbomify.com/CVE-2022-29188/index.md","name":"CVE-2022-29188","record":{"aliases":["GHSA-qwrf-gfpj-qvj6","GO-2022-0459"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"HTTP proxy","requires_auth":"none","summary":"Attackers can bypass the deny list in Smokescreen HTTP proxy by using square brackets around hostnames, allowing access to blocked URLs.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"smokescreen","vendor":"stripe"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Smokescreen is an HTTP proxy. 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 surrounding the hostname with square brackets (e.g. `[example.com]`). This only impacted the HTTP proxy functionality of Smokescreen. HTTPS requests were not impacted. Smokescreen version 0.0.4 contains a patch for this issue.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Smokescreen SSRF via deny list bypass (square brackets) in Smokescreen","id":"CVE-2022-29188","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"ssrf","year":"2022"},"n_packages":3,"n_references":2,"next":{"headline":"Buffer for inbound DTLS fragments has no limit","id":"CVE-2022-29189"},"packages":[{"ecosystem":"Go","fixed":["0.0.4"],"introduced":["0"],"last_affected":[],"package":"github.com/stripe/smokescreen","purl":null,"source":"GHSA-qwrf-gfpj-qvj6"},{"ecosystem":"Go","fixed":["0.0.4"],"introduced":["0"],"last_affected":[],"package":"github.com/stripe/smokescreen","purl":"pkg:golang/github.com/stripe/smokescreen","source":"GHSA-qwrf-gfpj-qvj6"},{"ecosystem":"Go","fixed":["0.0.4"],"introduced":["0"],"last_affected":[],"package":"github.com/stripe/smokescreen","purl":"pkg:golang/github.com/stripe/smokescreen","source":"GO-2022-0459"}],"prev":{"headline":"Bypass of safe.directory protections in Git","id":"CVE-2022-29187"},"products":["smokescreen"],"published":"2022-05-20","related":[{"cvss_score":5.8,"headline":"Smokescreen SSRF via deny list bypass","id":"CVE-2022-24825","kev_date_added":null,"published":"2022-04-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["stripe"]},"summary":"Attackers can bypass the deny list in Smokescreen HTTP proxy by using square brackets around hostnames, allowing access to blocked URLs.","url":"https://insights.sbomify.com/CVE-2022-29188/"}
