{"id":"CVE-2026-34224","aliases":["BIT-parse-2026-34224","GHSA-w73w-g5xw-rwhf"],"url":"https://o3.security/vulnerability/CVE-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-alpha.8, 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-alpha.8.","published":"2026-03-31T14:25:22.782Z","modified":"2026-08-07T11:50:57.645977155Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"9.7.0-alpha.8"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"8.6.64"}],"fix":{"url":"https://github.com/parse-community/parse-server/commit/661f160edac8daac0486bc94413cf9652876ab92","label":"parse-community/parse-server@661f160"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34224.json"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-w73w-g5xw-rwhf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34224"},{"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:57.645977155Z"}}
