A denial of service vulnerability has been discovered in verions 2.8.3 through 2.8.15 of Play's forms library, in both the Scala and Java APIs. This can occur when using either the `Form#bindFromRequest` method on a JSON request body or the `Form#bind` method directly on a JSON value. If the JSON data being bound to the form contains a deeply-nested JSON object or array, the form binding implementation may consume all available heap space and cause an `OutOfMemoryError`. If executing on the default dispatcher and `akka.jvm-exit-on-fatal-error` is enabled—as it is by default—then this can crash the application process. `Form.bindFromRequest` is vulnerable when using any body parser that produces a type of `AnyContent` or `JsValue` in Scala, or one that can produce a `JsonNode` in Java. This includes Play's default body parser. This vulnerability been patched in version 2.8.16. There is now a global limit on the depth of a JSON object that can be parsed, which can be configured by the user if necessary. As a workaround, applications that do not need to parse a request body of type `application/json` can switch from the default body parser to another body parser that supports only the specific type of body they expect.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-06-02 17:15:00","updated_at":"2022-06-13 12:26:00"},"problem_types":["CWE-400"],"metrics":[],"references":[{"url":"https://github.com/playframework/playframework/releases/tag/2.8.16","name":"https://github.com/playframework/playframework/releases/tag/2.8.16","refsource":"MISC","tags":[],"title":"Release Play 2.8.16 · playframework/playframework · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/playframework/playframework/security/advisories/GHSA-v8x6-59g4-5g3w","name":"https://github.com/playframework/playframework/security/advisories/GHSA-v8x6-59g4-5g3w","refsource":"CONFIRM","tags":[],"title":"Denial of service when binding forms from JSON · Advisory · playframework/playframework · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/playframework/playframework/pull/11301","name":"https://github.com/playframework/playframework/pull/11301","refsource":"MISC","tags":[],"title":"[2.8.x] add depth limit for JSON form binding by mkurz · Pull Request #11301 · playframework/playframework · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-31018","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31018","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"31018","vulnerable":"1","versionEndIncluding":"2.8.15","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"lightbend","cpe5":"play_framework","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-31018","STATE":"PUBLIC","TITLE":"Denial of service binding form from JSON in Play Framework"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"playframework","version":{"version_data":[{"version_value":">= 2.8.3, < 2.8.16"}]}}]},"vendor_name":"playframework"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"Play Framework is a web framework for Java and Scala.
