{"id":"CVE-2020-15149","details":"NodeBB before version 1.14.3 has a bug introduced in version 1.12.2 in the validation logic that makes it possible to change the password of any user on a running NodeBB forum by sending a specially crafted socket.io call to the server. This could lead to a privilege escalation event due via an account takeover. As a workaround you may cherry-pick the following commit from the project's repository to your running instance of NodeBB: 16cee1b03ba3eee177834a1fdac4aa8a12b39d2a. This is fixed in version 1.14.3.","modified":"2026-04-11T21:48:48.796250Z","published":"2020-08-20T01:17:12.337Z","related":["GHSA-hr66-c8pg-5mg7"],"references":[{"type":"ADVISORY","url":"http://packetstormsecurity.com/files/159560/NodeBB-Forum-1.14.2-Account-Takeover.html"},{"type":"ADVISORY","url":"https://zeroauth.ltd/blog/2020/08/20/proof-of-concept-exploit-for-cve-2020-15149-nodebb-arbitrary-user-password-change/"},{"type":"FIX","url":"https://github.com/NodeBB/NodeBB/commit/c2477d9d5ffc43e5ffeb537ea2ceb4ce9592aa39"},{"type":"FIX","url":"https://github.com/NodeBB/NodeBB/security/advisories/GHSA-hr66-c8pg-5mg7"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nodebb/nodebb","events":[{"introduced":"22db818eb40f04e528d95257c5517ded8341493d"},{"fixed":"668ad8abf753ffca24b31e07a390bb2c52d2d3c9"},{"fixed":"c2477d9d5ffc43e5ffeb537ea2ceb4ce9592aa39"}],"database_specific":{"extracted_events":[{"introduced":"1.12.2"},{"fixed":"1.14.3"}],"cpe":"cpe:2.3:a:nodebb:nodebb:*:*:*:*:*:*:*:*","source":["CPE_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-15149.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L"}]}
