Detailsinfo

A vulnerability, which was classified as problematic, was found in parse-community parse-server up to 8.6.32/9.0.0 9.6.0-alpha.6. Affected is an unknown function of the component Multi-Factor Authentication. The manipulation with an unknown input leads to a operation after expiration vulnerability. CWE is classifying the issue as CWE-672. The product uses, accesses, or otherwise operates on a resource after that resource has been expired, released, or revoked. This is going to have an impact on confidentiality. CVE summarizes:

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.7 and 8.6.33, when multi-factor authentication (MFA) via TOTP is enabled for a user account, Parse Server generates two single-use recovery codes. These codes are intended as a fallback when the user cannot provide a TOTP token. However, recovery codes are not consumed after use, allowing the same recovery code to be used an unlimited number of times. This defeats the single-use design of recovery codes and weakens the security of MFA-protected accounts. An attacker who obtains a single recovery code can repeatedly authenticate as the affected user without the code ever being invalidated. This vulnerability is fixed in 9.6.0-alpha.7 and 8.6.33.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-31875 since 03/09/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.

Upgrading to version 8.6.33 or 9.0.0 9.6.0-alpha.7 eliminates this vulnerability. The upgrade is hosted for download at github.com.
