{"id":"GHSA-j7mm-f4rv-6q6q","summary":"Parse Server has a protected fields bypass via LiveQuery subscription WHERE clause","details":"### Impact\n\nAn attacker can exploit LiveQuery subscriptions to infer the values of protected fields without directly receiving them. By subscribing with a WHERE clause that references a protected field (including via dot-notation or `$regex`), the attacker can observe whether LiveQuery events are delivered for matching objects. This creates a boolean oracle that leaks protected field values. The attack affects any class that has both `protectedFields` configured in Class-Level Permissions and LiveQuery enabled.\n\n### Patches\n\nThe fix adds validation of the LiveQuery subscription WHERE clause against the class's protected fields, mirroring the existing REST API validation. If a subscription's WHERE clause references a protected field directly, via dot-notation, or inside `$or` / `$and` / `$nor` operators, the subscription is rejected with a permission error. This is applied during subscription creation, so existing event delivery paths are not affected.\n\n### Workarounds\n\nDisable LiveQuery for classes that use `protectedFields` in their Class-Level Permissions, or remove `protectedFields` from classes that require LiveQuery.\n\n### References\n\n- GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-j7mm-f4rv-6q6q\n- Fix Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.6.0-alpha.9\n- Fix Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.35","aliases":["BIT-parse-2026-32098","CVE-2026-32098"],"modified":"2026-03-14T02:41:15.214625Z","published":"2026-03-12T14:20:02Z","database_specific":{"cwe_ids":["CWE-200"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-03-12T14:20:02Z","nvd_published_at":"2026-03-11T20:16:18Z"},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-j7mm-f4rv-6q6q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32098"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/8.6.35"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/9.6.0-alpha.9"}],"affected":[{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0"},{"fixed":"9.6.0-alpha.9"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-j7mm-f4rv-6q6q/GHSA-j7mm-f4rv-6q6q.json"}},{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.35"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-j7mm-f4rv-6q6q/GHSA-j7mm-f4rv-6q6q.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
