{"cve":"CVE-2026-31828","nvd":{"published":"2026-03-10T22:16:20.783","modified":"2026-06-17T10:34:32.057","status":"Analyzed","description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.13 and 8.6.26, the LDAP authentication adapter is vulnerable to LDAP injection. User-supplied input (authData.id) is interpolated directly into LDAP Distinguished Names (DN) and group search filters without escaping special characters. This allows an attacker with valid LDAP credentials to manipulate the bind DN structure and to bypass group membership checks. This enables privilege escalation from any authenticated LDAP user to a member of any restricted group. The vulnerability affects Parse Server deployments that use the LDAP authentication adapter with group-based access control. This vulnerability is fixed in 9.5.2-alpha.13 and 8.6.26.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":6.0},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-90"],"references":["https://github.com/parse-community/parse-server/releases/tag/8.6.26","https://github.com/parse-community/parse-server/releases/tag/9.5.2-alpha.13","https://github.com/parse-community/parse-server/security/advisories/GHSA-7m6r-fhh7-r47c"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-31828","score":0.00449,"percentile":0.39047,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7m6r-fhh7-r47c","url":"https://osv.dev/vulnerability/GHSA-7m6r-fhh7-r47c","summary":"Parse Server vulnerable to LDAP injection via unsanitized user input in DN and group filter construction","modified":"2026-03-14T03:41:10.943365Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0-alpha.1 <9.5.2-alpha.13"],"fixed":["9.5.2-alpha.13"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.26"],"fixed":["8.6.26"]}]}],"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).
