{"cve":"CVE-2022-31018","nvd":{"published":"2022-06-02T17:15:07.617","modified":"2026-06-17T04:44:36.950","status":"Modified","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://github.com/playframework/playframework/pull/11301","https://github.com/playframework/playframework/releases/tag/2.8.16","https://github.com/playframework/playframework/security/advisories/GHSA-v8x6-59g4-5g3w","https://github.com/playframework/playframework/pull/11301","https://github.com/playframework/playframework/releases/tag/2.8.16"],"products":["lightbend:play_framework"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-31018","score":0.01722,"percentile":0.77493,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-v8x6-59g4-5g3w","url":"https://osv.dev/vulnerability/GHSA-v8x6-59g4-5g3w","summary":"Denial of service binding form from JSON in Play Framework","modified":"2023-11-08T04:09:22.656879Z","packages":[{"ecosystem":"Maven","name":"com.typesafe.play:play_2.13","purl":"pkg:maven/com.typesafe.play/play_2.13","ranges":[">=2.8.3 <2.8.16"],"fixed":["2.8.16"]},{"ecosystem":"Maven","name":"com.typesafe.play:play_2.12","purl":"pkg:maven/com.typesafe.play/play_2.12","ranges":[">=2.8.3 <2.8.16"],"fixed":["2.8.16"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
