Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-36319 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.vaadin:flow-server (Maven): affected from 3.0.0; fixed in 3.0.6\n- com.vaadin:flow-server (Maven): affected from 3.0.0; fixed in 3.0.6\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/CVE-2020-36319/ (Markdown: https://insights.sbomify.com/CVE-2020-36319/index.md)","id":"CVE-2020-36319","markdown":"https://insights.sbomify.com/CVE-2020-36319/index.md","name":"CVE-2020-36319","record":{"aliases":["GHSA-rjww-2x8v-m9v9"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Vaadin Java library","requires_auth":"low_privilege","summary":"Insecure default ObjectMapper configuration in Vaadin flow-server may expose sensitive data in applications using RestControllers.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Vaadin","cpe":[{"product":"flow","vendor":"vaadin"},{"product":"vaadin","vendor":"vaadin"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Insecure configuration of default ObjectMapper in com.vaadin:flow-server versions 3.0.0 through 3.0.5 (Vaadin 15.0.0 through 15.0.4) may expose sensitive data if the application also uses e.g. @RestController","ecosystems":["Maven"],"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":"Potential sensitive data exposure in applications using Vaadin 15","id":"CVE-2020-36319","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"information_disclosure","year":"2020"},"n_packages":2,"n_references":3,"next":{"headline":"Regular expression Denial of Service (ReDoS) in EmailValidator class in Vaadin 7","id":"CVE-2020-36320"},"packages":[{"ecosystem":"Maven","fixed":["3.0.6"],"introduced":["3.0.0"],"last_affected":[],"package":"com.vaadin:flow-server","purl":null,"source":"GHSA-rjww-2x8v-m9v9"},{"ecosystem":"Maven","fixed":["3.0.6"],"introduced":["3.0.0"],"last_affected":[],"package":"com.vaadin:flow-server","purl":"pkg:maven/com.vaadin/flow-server","source":"GHSA-rjww-2x8v-m9v9"}],"prev":{"headline":"Use after free in n/a","id":"CVE-2020-36318"},"products":["Vaadin","flow-server"],"published":"2021-04-23","related":[{"cvss_score":8.6,"headline":"Server classes and resources exposure in OSGi applications using Vaadin 12-14 and 19","id":"CVE-2021-31407","kev_date_added":null,"published":"2021-04-23"},{"cvss_score":7.5,"headline":"Regular expression denial of service (ReDoS) in EmailField component in Vaadin 14 and 15-17","id":"CVE-2021-31405","kev_date_added":null,"published":"2021-04-23"},{"cvss_score":6.3,"headline":"Insecure temporary directory usage in frontend build functionality of Vaadin 14 and 15-19","id":"CVE-2021-31411","kev_date_added":null,"published":"2021-05-05"},{"cvss_score":6.3,"headline":"Server session is not invalidated when logout() helper method of Authentication module is used in Vaadin 18-19","id":"CVE-2021-31408","kev_date_added":null,"published":"2021-04-23"},{"cvss_score":6.1,"headline":"Reflected cross-site scripting in default RouteNotFoundError view in Vaadin 10 and 11-13","id":"CVE-2019-25027","kev_date_added":null,"published":"2021-04-23"},{"cvss_score":5.9,"headline":"Directory traversal in development mode handler in Vaadin 14 and 15-17","id":"CVE-2020-36321","kev_date_added":null,"published":"2021-04-23"},{"cvss_score":5.3,"headline":"Possible route enumeration in production mode via RouteNotFoundError view in Vaadin 10, 11-14, and 15-19","id":"CVE-2021-31412","kev_date_added":null,"published":"2021-06-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Vaadin"]},"summary":"Insecure default ObjectMapper configuration in Vaadin flow-server may expose sensitive data in applications using RestControllers.","url":"https://insights.sbomify.com/CVE-2020-36319/"}
