Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-16468 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- loofah (RubyGems): affected all versions; fixed in 2.2.3\n- loofah (RubyGems): affected all versions; fixed in 2.2.3\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-2018-16468/ (Markdown: https://insights.sbomify.com/CVE-2018-16468/index.md)","id":"CVE-2018-16468","markdown":"https://insights.sbomify.com/CVE-2018-16468/index.md","name":"CVE-2018-16468","record":{"aliases":["DEBIAN-CVE-2018-16468","DSA-4364-1","GHSA-g4xq-jx4w-4cjv","SUSE-SU-2018:3928-1","UBUNTU-CVE-2018-16468"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby HTML sanitizer","requires_auth":"low_privilege","summary":"Attackers can inject malicious JavaScript into sanitized output via crafted SVG elements, leading to XSS in applications using the Loofah gem.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"loofah","vendor":"loofah_project"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In the Loofah gem for Ruby, through v2.2.2, unsanitized JavaScript may occur in sanitized output when a crafted SVG element is republished.","ecosystems":["RubyGems","SUSE:Linux Enterprise High Availability Extension 15"],"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":"Loofah Cross-site Scripting vulnerability","id":"CVE-2018-16468","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"xss","year":"2018"},"n_packages":3,"n_references":2,"next":{"headline":"Prototype Pollution in merge","id":"CVE-2018-16469"},"packages":[{"ecosystem":"RubyGems","fixed":["2.2.3"],"introduced":["0"],"last_affected":[],"package":"loofah","purl":null,"source":"GHSA-g4xq-jx4w-4cjv"},{"ecosystem":"RubyGems","fixed":["2.2.3"],"introduced":["0"],"last_affected":[],"package":"loofah","purl":"pkg:gem/loofah","source":"GHSA-g4xq-jx4w-4cjv"},{"ecosystem":"SUSE:Linux Enterprise High Availability Extension 15","fixed":["2.2.2-4.3.1"],"introduced":["0"],"last_affected":[],"package":"rubygem-loofah","purl":"pkg:rpm/suse/rubygem-loofah\u0026distro=SUSE%20Linux%20Enterprise%20High%20Availability%20Extension%2015","source":"SUSE-SU-2018:3928-1"}],"prev":{"headline":"Missing authorization in Nextcloud Server","id":"CVE-2018-16467"},"products":["Loofah (Ruby Gem)"],"published":"2018-10-30","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":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"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":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can inject malicious JavaScript into sanitized output via crafted SVG elements, leading to XSS in applications using the Loofah gem.","url":"https://insights.sbomify.com/CVE-2018-16468/"}
