{"id":"BIT-parse-2026-34224","summary":"Parse Server: MFA single-use token bypass via concurrent authData login requests","details":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.64 and 9.7.0, an attacker who possesses a valid authentication provider token and a single MFA recovery code or SMS one-time password can create multiple authenticated sessions by sending concurrent login requests via the authData login endpoint. This defeats the single-use guarantee of MFA recovery codes and SMS one-time passwords, allowing session persistence even after the legitimate user revokes detected sessions. This issue has been patched in versions 8.6.64 and 9.7.0.","aliases":["CVE-2026-34224","GHSA-w73w-g5xw-rwhf"],"modified":"2026-09-10T16:01:44.866093540Z","published":"2026-04-06T14:49:26.245Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*"]},"references":[{"type":"FIX","url":"https://github.com/parse-community/parse-server/commit/661f160edac8daac0486bc94413cf9652876ab92"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/commit/e7efbebba398ce6abe5b6b6fb9829c6ebe310fbf"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10326"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10327"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-w73w-g5xw-rwhf"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34224"}],"affected":[{"package":{"name":"parse","ecosystem":"Bitnami","purl":"pkg:bitnami/parse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.64"},{"introduced":"9.0.0"},{"fixed":"9.7.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/parse/BIT-parse-2026-34224.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:N"}]}],"schema_version":"1.9.0"}
