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.\n\n### Patches\nRemove session token from LiveQuery payload.\n\n### Workaround\nSet `user.acl(new Parse.ACL())` in a beforeSave trigger to make the user private already on sign-up.","aliases":["BIT-parse-2021-41109","CVE-2021-41109"],"modified":"2026-05-07T05:03:01.103226873Z","published":"2021-09-30T17:09:47Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-09-30T16:43:12Z","nvd_published_at":"2021-09-30T15:15:00Z","cwe_ids":["CWE-200"]},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-7pr3-p5fm-8r9x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-41109"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/4ac4b7f71002ed4fbedbb901db1f6ed1e9ac5559"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/4.10.4"}],"affected":[{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.10.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/09/GHSA-7pr3-p5fm-8r9x/GHSA-7pr3-p5fm-8r9x.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
