An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-8167 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- actionview (RubyGems): affected from 5.0.0; fixed in 5.2.4.3\n- actionview (RubyGems): affected from 5.0.0; fixed in 5.2.4.3\n- actionview (RubyGems): affected from 6.0.0; fixed in 6.0.3.1\n- actionview (RubyGems): affected from 6.0.0; fixed in 6.0.3.1\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-2020-8167/ (Markdown: https://insights.sbomify.com/CVE-2020-8167/index.md)","id":"CVE-2020-8167","markdown":"https://insights.sbomify.com/CVE-2020-8167/index.md","name":"CVE-2020-8167","record":{"aliases":["DEBIAN-CVE-2020-8167","GHSA-xq5j-gw7f-jgj8","UBUNTU-CVE-2020-8167"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby on Rails","requires_auth":"none","summary":"Attackers can exploit a CSRF flaw in the rails-ujs module to send tokens to wrong domains, bypassing security protections.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"rails","vendor":"rubyonrails"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A CSRF vulnerability exists in rails \u003c= 6.0.3 rails-ujs module that could allow attackers to send CSRF tokens to wrong domains.","ecosystems":["RubyGems"],"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":"CSRF Vulnerability in rails-ujs","id":"CVE-2020-8167","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"debian:debian_linux","products":["debian:debian_linux","rubyonrails:rails"],"type":"csrf","year":"2020"},"n_packages":4,"n_references":3,"next":{"headline":"Cross-site request forgery in AirMax AirOS for TI, XW and XM boards","id":"CVE-2020-8168"},"packages":[{"ecosystem":"RubyGems","fixed":["5.2.4.3"],"introduced":["5.0.0"],"last_affected":[],"package":"actionview","purl":null,"source":"GHSA-xq5j-gw7f-jgj8"},{"ecosystem":"RubyGems","fixed":["5.2.4.3"],"introduced":["5.0.0"],"last_affected":[],"package":"actionview","purl":"pkg:gem/actionview","source":"GHSA-xq5j-gw7f-jgj8"},{"ecosystem":"RubyGems","fixed":["6.0.3.1"],"introduced":["6.0.0"],"last_affected":[],"package":"actionview","purl":null,"source":"GHSA-xq5j-gw7f-jgj8"},{"ecosystem":"RubyGems","fixed":["6.0.3.1"],"introduced":["6.0.0"],"last_affected":[],"package":"actionview","purl":"pkg:gem/actionview","source":"GHSA-xq5j-gw7f-jgj8"}],"prev":{"headline":"Ability to forge per-form CSRF tokens in Rails","id":"CVE-2020-8166"},"products":["http://github.com/rails/rails"],"published":"2020-06-19","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can exploit a CSRF flaw in the rails-ujs module to send tokens to wrong domains, bypassing security protections.","url":"https://insights.sbomify.com/CVE-2020-8167/"}
