{"id":"GHSA-v8x6-59g4-5g3w","summary":"Denial of service binding form from JSON in Play Framework","details":"### Impact\n\nA denial-of-service vulnerability has been discovered in 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.\n\n`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.\n\n### Patches\n\nThis 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.\n\n### Workarounds\n\nApplications 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; for example, the `formUrlEncoded` body parser can be used if the Play action only needs to accept `application/x-www-form-urlencoded`.\n\n","aliases":["CVE-2022-31018"],"modified":"2023-11-01T04:58:54.486086Z","published":"2022-06-03T22:18:58Z","database_specific":{"cwe_ids":["CWE-400"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2022-06-03T22:18:58Z","nvd_published_at":"2022-06-02T17:15:00Z"},"references":[{"type":"WEB","url":"https://github.com/playframework/playframework/security/advisories/GHSA-v8x6-59g4-5g3w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31018"},{"type":"WEB","url":"https://github.com/playframework/playframework/pull/11301"},{"type":"PACKAGE","url":"https://github.com/playframework/playframework"},{"type":"WEB","url":"https://github.com/playframework/playframework/releases/tag/2.8.16"}],"affected":[{"package":{"name":"com.typesafe.play:play_2.13","ecosystem":"Maven","purl":"pkg:maven/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"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/06/GHSA-v8x6-59g4-5g3w/GHSA-v8x6-59g4-5g3w.json"}},{"package":{"name":"com.typesafe.play:play_2.12","ecosystem":"Maven","purl":"pkg:maven/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"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/06/GHSA-v8x6-59g4-5g3w/GHSA-v8x6-59g4-5g3w.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
