{"id":"CVE-2021-41109","aliases":["BIT-parse-2021-41109","GHSA-7pr3-p5fm-8r9x"],"url":"https://o3.security/vulnerability/CVE-2021-41109","summary":"LiveQuery publishes user session tokens in parse-server","details":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to version 4.10.4, for regular (non-LiveQuery) queries, the session token is removed from the response, but for LiveQuery payloads it is currently not. If a user has a LiveQuery subscription on the `Parse.User` class, all session tokens created during user sign-ups will be broadcast as part of the LiveQuery payload. A patch in version 4.10.4 removes session tokens from the LiveQuery payload. As a workaround, set `user.acl(new Parse.ACL())` in a beforeSave trigger to make the user private already on sign-up.","published":"2021-09-30T15:15:07.730Z","modified":"2026-08-07T17:02:50.803346Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.01246,"percentile":0.67548,"asOf":"2026-09-11"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"4.10.4"}],"fix":{"url":"https://github.com/parse-community/parse-server/commit/4ac4b7f71002ed4fbedbb901db1f6ed1e9ac5559","label":"parse-community/parse-server@4ac4b7f"},"references":[{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/releases/tag/4.10.4"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-7pr3-p5fm-8r9x"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/commit/4ac4b7f71002ed4fbedbb901db1f6ed1e9ac5559"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-41109"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T17:02:50.803346Z"}}
