{"id":"CVE-2022-31018","aliases":["EUVD-2022-6163","GHSA-v8x6-59g4-5g3w"],"status":"published","title":"Denial of service binding form from JSON in Play Framework","description":"Play Framework is a web framework for Java and Scala. 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.","severity":{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.01722,"percentile":0.77684,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-400"],"published":"2022-06-02T16:45:13Z","modified":"2026-10-28T02:31:01Z","fixes":[{"ecosystem":"Maven","package":"com.typesafe.play:play_2.13","fixed_in":["2.8.16"],"sources":["ghsa","osv"]},{"ecosystem":"Maven","package":"com.typesafe.play:play_2.12","fixed_in":["2.8.16"],"sources":["ghsa","osv"]}],"affected":[{"source":"ghsa","ecosystem":"Maven","package":"com.typesafe.play:play_2.13","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.8.3"},{"fixed":"2.8.16"}]}]},{"source":"ghsa","ecosystem":"Maven","package":"com.typesafe.play:play_2.12","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.8.3"},{"fixed":"2.8.16"}]}]},{"source":"osv","ecosystem":"Maven","package":"com.typesafe.play:play_2.13","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.8.3"},{"fixed":"2.8.16"}]}],"versions":["2.8.10","2.8.11","2.8.12","2.8.13","2.8.14","2.8.15","2.8.3","2.8.4","2.8.5","2.8.6","2.8.7","2.8.8","2.8.8-RC1","2.8.9","2.8.9-RC1"]},{"source":"osv","ecosystem":"Maven","package":"com.typesafe.play:play_2.12","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.8.3"},{"fixed":"2.8.16"}]}],"versions":["2.8.10","2.8.11","2.8.12","2.8.13","2.8.14","2.8.15","2.8.3","2.8.4","2.8.5","2.8.6","2.8.7","2.8.8","2.8.8-RC1","2.8.9","2.8.9-RC1"]}],"products":[{"vendor":"lightbend","product":"play_framework"},{"vendor":"playframework","product":"playframework"}],"references":[{"url":"https://github.com/playframework/playframework/security/advisories/GHSA-v8x6-59g4-5g3w","tags":["x_refsource_CONFIRM","x_transferred","Mitigation","Third Party Advisory","advisory","web"]},{"url":"https://github.com/playframework/playframework/pull/11301","tags":["x_refsource_MISC","x_transferred","Patch","Third Party Advisory","fix","web"]},{"url":"https://github.com/playframework/playframework/releases/tag/2.8.16","tags":["x_refsource_MISC","x_transferred","Release Notes","Third Party Advisory","web"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31018","tags":["advisory"]},{"url":"https://github.com/advisories/GHSA-v8x6-59g4-5g3w"},{"url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31018.json","tags":["advisory"]},{"url":"https://github.com/playframework/playframework","tags":["package"]}],"sources":{"cve":[{"id":"CVE-2022-31018","title":"Denial of service binding form from JSON in Play Framework","description":"Play Framework is a web framework for Java and Scala.
