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-2020-6420 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-6420/ (Markdown: https://insights.sbomify.com/CVE-2020-6420/index.md)","id":"CVE-2020-6420","markdown":"https://insights.sbomify.com/CVE-2020-6420/index.md","name":"CVE-2020-6420","record":{"aliases":["DEBIAN-CVE-2020-6420","GHSA-r4jm-xf8w-3f3v","RHSA-2020:0779","UBUNTU-CVE-2020-6420","openSUSE-SU-2020:0322-1","openSUSE-SU-2020:0324-1"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Google Chrome","requires_auth":"none","summary":"Remote attackers can bypass same-origin policy in Google Chrome via crafted HTML pages, potentially accessing restricted data.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"chrome","vendor":"google"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Insufficient policy enforcement in media in Google Chrome prior to 80.0.3987.132 allowed a remote attacker to bypass same origin policy via a crafted HTML page.","ecosystems":["Red Hat:rhel_extras:6","SUSE:Package Hub 12 SP3","openSUSE:Leap 15.1"],"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":"Security feature bypass in Chrome","id":"CVE-2020-6420","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora","google:chrome"],"type":"security_feature_bypass","year":"2020"},"n_packages":4,"n_references":3,"next":{"headline":"Use after free in Chrome","id":"CVE-2020-6422"},"packages":[{"ecosystem":"Red Hat:rhel_extras:6","fixed":["0:80.0.3987.132-1.el6_10"],"introduced":["0"],"last_affected":[],"package":"chromium-browser","purl":"pkg:rpm/redhat/chromium-browser","source":"RHSA-2020:0779"},{"ecosystem":"Red Hat:rhel_extras:6","fixed":["0:80.0.3987.132-1.el6_10"],"introduced":["0"],"last_affected":[],"package":"chromium-browser-debuginfo","purl":"pkg:rpm/redhat/chromium-browser-debuginfo","source":"RHSA-2020:0779"},{"ecosystem":"SUSE:Package Hub 12 SP3","fixed":["80.0.3987.132-37.1"],"introduced":["0"],"last_affected":[],"package":"chromium","purl":"pkg:rpm/suse/chromium\u0026distro=SUSE%20Package%20Hub%2012%20SP3","source":"openSUSE-SU-2020:0324-1"},{"ecosystem":"openSUSE:Leap 15.1","fixed":["80.0.3987.132-lp151.2.69.1"],"introduced":["0"],"last_affected":[],"package":"chromium","purl":"pkg:rpm/opensuse/chromium\u0026distro=openSUSE%20Leap%2015.1","source":"openSUSE-SU-2020:0322-1"}],"prev":{"headline":"Memory corruption in Chrome","id":"CVE-2020-6419"},"products":["Chrome"],"published":"2020-03-20","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":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Google"]},"summary":"Remote attackers can bypass same-origin policy in Google Chrome via crafted HTML pages, potentially accessing restricted data.","url":"https://insights.sbomify.com/CVE-2020-6420/"}
