Prior to 9.6.0-alpha.6 and 8.6.32, the protectedFields class-level permission (CLP) can be bypassed using dot-notation in query WHERE clauses and sort parameters. An attacker can use dot-notation to query or sort by sub-fields of a protected field, enabling a binary oracle attack to enumerate protected field values. This affects both MongoDB and PostgreSQL deployments. This vulnerability is fixed in 9.6.0-alpha.6 and 8.6.32.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-284"],"references":["https://github.com/parse-community/parse-server/releases/tag/8.6.32","https://github.com/parse-community/parse-server/releases/tag/9.6.0-alpha.6","https://github.com/parse-community/parse-server/security/advisories/GHSA-r2m8-pxm9-9c4g"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-31872","score":0.00382,"percentile":0.32222,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r2m8-pxm9-9c4g","url":"https://osv.dev/vulnerability/GHSA-r2m8-pxm9-9c4g","summary":"Parse Server has a protected fields bypass via dot-notation in query and sort","modified":"2026-03-13T13:10:57.234333Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0-alpha.1 <9.6.0-alpha.6"],"fixed":["9.6.0-alpha.6"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.32"],"fixed":["8.6.32"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
