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 GHSA-jqj4-r483-4gvr in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.vaadin:vaadin-bom (Maven): affected from 10.0.0; fixed in 10.0.14\n- com.vaadin:vaadin-bom (Maven): affected from 10.0.0; fixed in 10.0.14\n- com.vaadin:vaadin-bom (Maven): affected from 11.0.0; fixed in 13.0.6\n- com.vaadin:vaadin-bom (Maven): affected from 11.0.0; fixed in 13.0.6\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/GHSA-jqj4-r483-4gvr/ (Markdown: https://insights.sbomify.com/GHSA-jqj4-r483-4gvr/index.md)","id":"GHSA-jqj4-r483-4gvr","markdown":"https://insights.sbomify.com/GHSA-jqj4-r483-4gvr/index.md","name":"GHSA-jqj4-r483-4gvr","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Vaadin flow-server","requires_auth":"none","summary":"Attackers can execute malicious JavaScript in user browsers via crafted URLs due to missing output sanitization in the default RouteNotFoundError view.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Missing output sanitization in default `RouteNotFoundError` view in `com.vaadin:flow-server` versions 1.0.0 through 1.0.10 (Vaadin 10.0.0 through 10.0.13), and 1.1.0 through 1.4.2 (Vaadin 11.0.0 through 13.0.5) allows attacker to execute malicious JavaScript via crafted URL.\n\n- https://vaadin.com/security/cve-2019-25027","ecosystems":["Maven"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Reflected cross-site scripting in default RouteNotFoundError view in Vaadin 10 and 11-13","id":"GHSA-jqj4-r483-4gvr","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":4,"n_references":null,"packages":[{"ecosystem":"Maven","fixed":["10.0.14"],"introduced":["10.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":null,"source":"GHSA-jqj4-r483-4gvr"},{"ecosystem":"Maven","fixed":["10.0.14"],"introduced":["10.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":"pkg:maven/com.vaadin/vaadin-bom","source":"GHSA-jqj4-r483-4gvr"},{"ecosystem":"Maven","fixed":["13.0.6"],"introduced":["11.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":null,"source":"GHSA-jqj4-r483-4gvr"},{"ecosystem":"Maven","fixed":["13.0.6"],"introduced":["11.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":"pkg:maven/com.vaadin/vaadin-bom","source":"GHSA-jqj4-r483-4gvr"}],"products":null,"published":"2021-04-19","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Attackers can execute malicious JavaScript in user browsers via crafted URLs due to missing output sanitization in the default RouteNotFoundError view.","url":"https://insights.sbomify.com/GHSA-jqj4-r483-4gvr/"}
