An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-c6c4-7x48-4cqp 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 10.0.17\n- com.vaadin:vaadin-bom (Maven): affected from 10.0.0; fixed in 10.0.17\n- com.vaadin:vaadin-bom (Maven): affected from 11.0.0; fixed in 14.4.7\n- com.vaadin:vaadin-bom (Maven): affected from 11.0.0; fixed in 14.4.7\n- com.vaadin:vaadin-bom (Maven): affected from 15.0.0; fixed in 18.0.6\n- com.vaadin:vaadin-bom (Maven): affected from 15.0.0; fixed in 18.0.6\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-c6c4-7x48-4cqp/ (Markdown: https://insights.sbomify.com/GHSA-c6c4-7x48-4cqp/index.md)","id":"GHSA-c6c4-7x48-4cqp","markdown":"https://insights.sbomify.com/GHSA-c6c4-7x48-4cqp/index.md","name":"GHSA-c6c4-7x48-4cqp","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Vaadin Flow Server","requires_auth":"none","summary":"Attackers can bypass CSRF protection by guessing security tokens via timing side-channel attacks in the UIDL request handler.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Non-constant-time comparison of CSRF tokens in UIDL request handler in `com.vaadin:flow-server` versions 1.0.0 through 1.0.13 (Vaadin 10.0.0 through 10.0.16), 1.1.0 prior to 2.0.0 (Vaadin 11 prior to 14), 2.0.0 through 2.4.6 (Vaadin 14.0.0 through 14.4.6), 3.0.0 prior to 5.0.0 (Vaadin 15 prior to 18), and 5.0.0 through 5.0.2 (Vaadin 18.0.0 through 18.0.5) allows attacker to guess a security token via timing attack.\n\n- https://vaadin.com/security/cve-2021-31404","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":"Timing side channel vulnerability in UIDL request handler in Vaadin 10, 11-14, and 15-18","id":"GHSA-c6c4-7x48-4cqp","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Maven","product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":6,"n_references":null,"packages":[{"ecosystem":"Maven","fixed":["10.0.17"],"introduced":["10.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":null,"source":"GHSA-c6c4-7x48-4cqp"},{"ecosystem":"Maven","fixed":["10.0.17"],"introduced":["10.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":"pkg:maven/com.vaadin/vaadin-bom","source":"GHSA-c6c4-7x48-4cqp"},{"ecosystem":"Maven","fixed":["14.4.7"],"introduced":["11.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":null,"source":"GHSA-c6c4-7x48-4cqp"},{"ecosystem":"Maven","fixed":["14.4.7"],"introduced":["11.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":"pkg:maven/com.vaadin/vaadin-bom","source":"GHSA-c6c4-7x48-4cqp"},{"ecosystem":"Maven","fixed":["18.0.6"],"introduced":["15.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":null,"source":"GHSA-c6c4-7x48-4cqp"},{"ecosystem":"Maven","fixed":["18.0.6"],"introduced":["15.0.0"],"last_affected":[],"package":"com.vaadin:vaadin-bom","purl":"pkg:maven/com.vaadin/vaadin-bom","source":"GHSA-c6c4-7x48-4cqp"}],"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 bypass CSRF protection by guessing security tokens via timing side-channel attacks in the UIDL request handler.","url":"https://insights.sbomify.com/GHSA-c6c4-7x48-4cqp/"}
