CVE-2026-34224: Parseplatform Parse-Server

Medium severity, CVSS 4.4. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Parseplatform Parse-Server: before 8.6.64 (fixed in 8.6.64); from 9.0.0, before 9.7.0 (fixed in 9.7.0); version 9.7.0 only
