Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-3h5r-928v-mxhh 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 10.0.8\n- com.vaadin:vaadin-bom (Maven): affected from 10.0.0; fixed in 10.0.8\n- com.vaadin:vaadin-bom (Maven): affected from 11.0.0; fixed in 11.0.3\n- com.vaadin:vaadin-bom (Maven): affected from 11.0.0; fixed in 11.0.3\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/GHSA-3h5r-928v-mxhh/ (Markdown: https://insights.sbomify.com/GHSA-3h5r-928v-mxhh/index.md)","id":"GHSA-3h5r-928v-mxhh","markdown":"https://insights.sbomify.com/GHSA-3h5r-928v-mxhh/index.md","name":"GHSA-3h5r-928v-mxhh","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Vaadin Flow Server","requires_auth":"low_privilege","summary":"An attacker can modify client-side element properties in Vaadin applications due to missing authorization checks in the UIDL request handler.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Missing check in UIDL request handler in `com.vaadin:flow-server` versions 1.0.0 through 1.0.5 (Vaadin 10.0.0 through 10.0.7, and 11.0.0 through 11.0.2) allows attacker to update element property values via crafted synchronization message.\n\n- https://vaadin.com/security/cve-2018-25007","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":"Unauthorized client-side property update in UIDL request handler in Vaadin 10 and 11","id":"GHSA-3h5r-928v-mxhh","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":4,"n_references":null,"packages":[{"ecosystem":"Maven","fixed":["10.0.8"],"introduced":["10.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":null,"source":"GHSA-3h5r-928v-mxhh"},{"ecosystem":"Maven","fixed":["10.0.8"],"introduced":["10.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":"pkg:maven/com.vaadin/vaadin-bom","source":"GHSA-3h5r-928v-mxhh"},{"ecosystem":"Maven","fixed":["11.0.3"],"introduced":["11.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":null,"source":"GHSA-3h5r-928v-mxhh"},{"ecosystem":"Maven","fixed":["11.0.3"],"introduced":["11.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":"pkg:maven/com.vaadin/vaadin-bom","source":"GHSA-3h5r-928v-mxhh"}],"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":"An attacker can modify client-side element properties in Vaadin applications due to missing authorization checks in the UIDL request handler.","url":"https://insights.sbomify.com/GHSA-3h5r-928v-mxhh/"}
