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-2020-36569 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/nanobox-io/golang-nanoauth (Go): affected from 0.0.0-20160722212129-ac0cc4484ad4; fixed in 0.0.0-20200131131040-063a3fb69896\n- github.com/nanobox-io/golang-nanoauth (Go): affected from 0.0.0-20160722212129-ac0cc4484ad4; fixed in 0.0.0-20200131131040-063a3fb69896\n- github.com/nanobox-io/golang-nanoauth (Go): affected from 0.0.0-20160722212129-ac0cc4484ad4; fixed in 0.0.0-20200131131040-063a3fb69896\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-2020-36569/ (Markdown: https://insights.sbomify.com/CVE-2020-36569/index.md)","id":"CVE-2020-36569","markdown":"https://insights.sbomify.com/CVE-2020-36569/index.md","name":"CVE-2020-36569","record":{"aliases":["GHSA-hrm3-3xm6-x33h","GO-2020-0004"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Go authentication library","requires_auth":"none","summary":"Attackers can bypass authentication in the golang-nanoauth library if the server is configured with an empty token.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Go","cpe":[{"product":"golang-nanoauth","vendor":"digitalocean"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Authentication is globally bypassed in github.com/nanobox-io/golang-nanoauth between v0.0.0-20160722212129-ac0cc4484ad4 and v0.0.0-20200131131040-063a3fb69896 if ListenAndServe is called with an empty token.","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":"Authentication bypass in github.com/nanobox-io/golang-nanoauth","id":"CVE-2020-36569","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":3,"n_references":3,"next":{"headline":"OmniAuth's `lib/omniauth/failure_endpoint.rb` does not escape `message_key` value","id":"CVE-2020-36599"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20200131131040-063a3fb69896"],"introduced":["0.0.0-20160722212129-ac0cc4484ad4"],"last_affected":[],"package":"github.com/nanobox-io/golang-nanoauth","purl":null,"source":"GHSA-hrm3-3xm6-x33h"},{"ecosystem":"Go","fixed":["0.0.0-20200131131040-063a3fb69896"],"introduced":["0.0.0-20160722212129-ac0cc4484ad4"],"last_affected":[],"package":"github.com/nanobox-io/golang-nanoauth","purl":"pkg:golang/github.com/nanobox-io/golang-nanoauth","source":"GHSA-hrm3-3xm6-x33h"},{"ecosystem":"Go","fixed":["0.0.0-20200131131040-063a3fb69896"],"introduced":["0.0.0-20160722212129-ac0cc4484ad4"],"last_affected":[],"package":"github.com/nanobox-io/golang-nanoauth","purl":"pkg:golang/github.com/nanobox-io/golang-nanoauth","source":"GO-2020-0004"}],"prev":{"headline":"Resource exhaustion in github.com/revel/revel","id":"CVE-2020-36568"},"products":["github.com/nanobox-io/golang-nanoauth"],"published":"2022-12-27","related":[],"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":"total"},"state":"PUBLISHED","updated":"2025-04-11","vendors":["github.com/nanobox-io/golang-nanoauth"]},"summary":"Attackers can bypass authentication in the golang-nanoauth library if the server is configured with an empty token.","url":"https://insights.sbomify.com/CVE-2020-36569/"}
