{"id":"CVE-2026-32098","aliases":["BIT-parse-2026-32098","GHSA-j7mm-f4rv-6q6q"],"url":"https://o3.security/vulnerability/CVE-2026-32098","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","published":"2026-03-11T19:57:26.929Z","modified":"2026-08-12T03:51:21.815165503Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"9.6.0-alpha.9"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"8.6.35"}],"fix":null,"references":[{"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"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32098.json"},{"type":"ADVISORY","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:21.815165503Z"}}
