{"id":"CVE-2018-1000125","details":"inversoft prime-jwt version prior to version 1.3.0 or prior to commit 0d94dcef0133d699f21d217e922564adbb83a227 contains an input validation vulnerability in JWTDecoder.decode that can result in a JWT that is decoded and thus implicitly validated even if it lacks a valid signature. This attack appear to be exploitable via an attacker crafting a token with a valid header and body and then requests it to be validated. This vulnerability appears to have been fixed in 1.3.0 and later or after commit 0d94dcef0133d699f21d217e922564adbb83a227.","modified":"2026-07-08T14:58:10.292422Z","published":"2018-03-13T21:29:00.367Z","references":[{"type":"ADVISORY","url":"https://github.com/inversoft/prime-jwt/blob/master/CHANGES"},{"type":"ADVISORY","url":"https://github.com/inversoft/prime-jwt/issues/2"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ws-apps/prime-jwt","events":[{"introduced":"0"},{"fixed":"8011cd2a8eb64dd338fddf88e0e855b2a6b734e7"}],"database_specific":{"cpe":"cpe:2.3:a:inversoft:prime-jwt:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.3.0"}],"source":"CPE_RANGE"}}],"versions":["1.2.1","1.2.0","1.1.0","1.0.0","0.2.1","0.2.0","0.1.6","0.1.5","0.1.4","0.1.3","0.1.2","0.1.1","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-1000125.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
