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-2026-84357 in the wild and no public exploit code.\n\nAffected product: Google Chrome. 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-2026-84357/ (Markdown: https://insights.sbomify.com/CVE-2026-84357/index.md)","id":"CVE-2026-84357","markdown":"https://insights.sbomify.com/CVE-2026-84357/index.md","name":"CVE-2026-84357","record":{"aliases":["DEBIAN-CVE-2026-84357","ECHO-1b2e-fb75-76e4","GHSA-5j49-rh6r-4vvg","MINI-c8xg-xxqq-f7fj"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Google Chrome browser","requires_auth":"none","summary":"Remote attackers can bypass web origin policy in Google Chrome via crafted network traffic and social engineering, requiring an upgrade to mitigate.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"chrome","vendor":"google"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","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-20","name":"Improper Input Validation"}],"description":"Improper input validation in Omnibox in Google Chrome prior to 152.0.7977.75 allowed a remote attacker leveraging social engineering to bypass web origin policy via crafted network traffic.
