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-2022-34473 in the wild and no public exploit code.\n\nAffected product: Mozilla Firefox. 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-2022-34473/ (Markdown: https://insights.sbomify.com/CVE-2022-34473/index.md)","id":"CVE-2022-34473","markdown":"https://insights.sbomify.com/CVE-2022-34473/index.md","name":"CVE-2022-34473","record":{"aliases":["GHSA-h8wm-ccrj-94x5","UBUNTU-CVE-2022-34473"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Firefox browser","requires_auth":"none","summary":"An XSS vulnerability in Firefox's HTML Sanitizer allows attackers to execute arbitrary code via unsanitized xlink:href attributes in SVG use tags.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mozilla","cpe":[{"product":"firefox","vendor":"mozilla"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The HTML Sanitizer should have sanitized the \u003ccode\u003ehref\u003c/code\u003e attribute of SVG \u003ccode\u003e\u0026lt;use\u0026gt;\u003c/code\u003e tags; however it incorrectly did not sanitize \u003ccode\u003exlink:href\u003c/code\u003e attributes.
