{"id":"CVE-2022-31018","summary":"Denial of service binding form from JSON in Play Framework","details":"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.","aliases":["GHSA-v8x6-59g4-5g3w"],"modified":"2026-08-12T03:51:43.746892488Z","published":"2022-06-02T16:45:13Z","database_specific":{"cwe_ids":["CWE-400"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31018.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/playframework/playframework/releases/tag/2.8.16"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31018.json"},{"type":"ADVISORY","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":"FIX","url":"https://github.com/playframework/playframework/pull/11301"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/playframework/playframework","events":[{"introduced":"ce6ea559bdb787b96b68b4766df7653634acac15"},{"fixed":"296784bbbc28277f47ca8b91b366bda5f6f0fd04"}],"database_specific":{"cpe":"cpe:2.3:a:lightbend:play_framework:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"2.8.3"},{"last_affected":"2.8.15"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["2.8.15","2.8.14","2.8.13","2.8.12","2.8.11","2.8.10","2.8.9-RC1","2.8.9","2.8.8-RC1","2.8.8","2.8.7","2.8.6","2.8.5","2.8.4","2.8.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-31018.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"}]}
