{"id":"CVE-2019-9710","details":"An issue was discovered in webargs before 5.1.3, as used with marshmallow and other products. JSON parsing uses a short-lived cache to store the parsed JSON body. This cache is not thread-safe, meaning that incorrect JSON payloads could have been parsed for concurrent requests.","aliases":["GHSA-8554-jxcw-454q","PYSEC-2019-139"],"modified":"2026-04-10T04:20:59.561391Z","published":"2019-03-12T02:29:00.273Z","references":[{"type":"ADVISORY","url":"https://webargs.readthedocs.io/en/latest/changelog.html"},{"type":"REPORT","url":"https://github.com/marshmallow-code/webargs/issues/371"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/marshmallow-code/webargs","events":[{"introduced":"0"},{"fixed":"1c43dcaf1670cd5c6898c6297b489c2cdf87beb8"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"5.1.3"}]}}],"versions":["0.1.0","0.10.0","0.11.0","0.12.0","0.13.0","0.14.0","0.15.0","0.16.0","0.17.0","0.18.0","0.2.0","0.3.0","0.3.1","0.3.2","0.3.3","0.3.4","0.4.0","0.5.0","0.5.1","0.6.1","0.6.2","0.7.0","0.8.0","0.8.1","0.9.0","0.9.1","1.0.0","1.1.0","1.1.1","1.10.0","1.2.0","1.3.0","1.3.1","1.3.2","1.3.3","1.3.4","1.4.0","1.5.0","1.5.1","1.5.2","1.5.3","1.6.0","1.6.1","1.6.2","1.6.3","1.7.0","1.8.0","1.8.1","1.9.0","2.0.0","2.1.0","3.0.0","3.0.1","3.0.2","4.0.0","4.1.0","4.1.1","4.1.2","4.1.3","4.2.0","4.3.0","5.0.0","5.1.0","5.1.1","5.1.1.post0","5.1.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-9710.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
