{"id":"CVE-2019-12399","details":"When Connect workers in Apache Kafka 2.0.0, 2.0.1, 2.1.0, 2.1.1, 2.2.0, 2.2.1, or 2.3.0 are configured with one or more config providers, and a connector is created/updated on that Connect cluster to use an externalized secret variable in a substring of a connector configuration property value, then any client can issue a request to the same Connect cluster to obtain the connector's task configuration and the response will contain the plaintext secret rather than the externalized secrets variables.","aliases":["GHSA-6jmf-mxwf-r3jc"],"modified":"2026-04-10T04:15:30.066091Z","published":"2020-01-14T15:15:12.803Z","references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/r6af5ed95726874e9add022955be83c192428c248d1c9a1914aff89d9%40%3Cannounce.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rc27d424d0bdeaf31081c3e246db3c66e882243ae3f342dfa845e0261%40%3Ccommits.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r0e3a613705d70950aca2bfe9a6265c87503921852d9a3dbce512ca9f%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r4b20b40c40d4a4c641e2ef4228098a57935e5782bfdfdf3650e48265%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r9871a4215b621c1d09deee5eba97f0f44fde01b4363deb1bed0dd160%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rfe90ca0463c199b99c2921410639aed53a172ea8b733eab0dc776262%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r3154f5adbc905f1f9012a92240c8e00a96628470cc819453b9606d0e%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r47c225db363d1ee2c18c4b3b2f51b63a9789f78c7fa602e5976ecd05%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r6af5ed95726874e9add022955be83c192428c248d1c9a1914aff89d9%40%3Cusers.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rda253155601968331b5cf0da4f273813bbd91843c2568a8495d1c662%40%3Ccommits.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r2d390dec5f360ec8aa294bef18e1a4385e2a3698d747209216f5a48b%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r3203d7f25a6ca56ff3e48c43a6aa7cb60b8e5d57d0eed9f76dc2b7a8%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r56eb055b544931451283fee51f7e1f5b8ebd3085fed7d77aaba504c9%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r6fa1cff4786dcef2ddd1d717836ef123c878e8321c24855bad24ae0f%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r801c68bf987931f35d2e24ecc99f3aa2850fdd8f5ef15fe6c60fecf3%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r8890b8f18f1de821595792b58b968a89692a255bc20d86d395270740%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rde947ee866de6687bc51cdc8dfa6d7e6b3ad4ce8c708c344f773e6dc%40%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r4d9e87cdae99e98d7b244cfa53d9d2532d368d3a187fbc87c493dcbe%40%3Ccommits.druid.apache.org%3E"},{"type":"ADVISORY","url":"https://lists.apache.org/thread.html/r6af5ed95726874e9add022955be83c192428c248d1c9a1914aff89d9%40%3Cdev.kafka.apache.org%3E"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2020/01/14/1"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpujan2021.html"},{"type":"FIX","url":"https://www.oracle.com//security-alerts/cpujul2021.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/kafka","events":[{"introduced":"0"},{"last_affected":"3402a8361b7347326b8a9fdb22300986fbbf9cd0"},{"introduced":"0"},{"last_affected":"fa14705e51bd2ce538ed9f1ec431eb24528a4819"},{"introduced":"0"},{"last_affected":"809be928f1ae004e11d65c307ea322bef126c834"},{"introduced":"0"},{"last_affected":"21234bee31165527859b46ea48c46b76532f7a37"},{"introduced":"0"},{"last_affected":"05fcfde8f69b0349216553f711fdfc3f0259c601"},{"introduced":"0"},{"last_affected":"55783d3133a5a49a0926eff027b75ae811f5e33b"},{"introduced":"0"},{"last_affected":"fc1aaa116b661c8a1a2eefc0ed7e92b7f2e27d35"},{"introduced":"0"},{"last_affected":"448719dc99a19793d55aaaa8b64282ed3fb3197d"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"2.0.0"},{"introduced":"0"},{"last_affected":"2.0.1"},{"introduced":"0"},{"last_affected":"2.1.0"},{"introduced":"0"},{"last_affected":"2.1.1"},{"introduced":"0"},{"last_affected":"2.2.0"},{"introduced":"0"},{"last_affected":"2.2.1"},{"introduced":"0"},{"last_affected":"2.3.0"},{"introduced":"0"},{"last_affected":"2.7.0"}]}}],"versions":["2.0.0","2.0.0-rc3","2.0.1","2.0.1-rc0","2.1.0","2.1.0-rc1","2.1.1","2.1.1-rc2","2.2.0","2.2.0-rc2","2.2.1","2.2.1-rc1","2.3.0","2.3.0-rc3","2.7.0","2.7.0-rc6"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"14.1.0"}]},{"events":[{"introduced":"0"},{"last_affected":"14.3.0"}]},{"events":[{"introduced":"0"},{"last_affected":"14.4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"14.1.0"}]},{"events":[{"introduce
