The vulnerability applies to the open\u2011source Parse Server that can run on any Node.js\u2011capable infrastructure.

From a technical standpoint, the endpoint performs an internal query that uses master-level authentication, and the master context leaks into the returned user data, circumventing the normal sanitization performed by the auth adapter. This results in a classic credential exposure vulnerability, classified as CWE-200. An attacker who obtains a valid session token can permanently extract MFA secrets and generate valid TOTP codes, effectively enabling ongoing account takeover.", "risk_and_exploitability": "The CVSS score of 7.1 reflects a medium\u2011to\u2011high impact, while the EPSS score below 1% indicates the chance of current exploitation is low. The vulnerability is not presently listed in CISA\u2019s KEV catalog. Exploitation requires an attacker to possess a legitimate user\u2019s session token, which can be obtained through credential compromise, phishing, or session hijacking. Once the token is held, the attacker can repeatedly call GET /users/me and harvest MFA secrets, gaining indefinite access to the victim\u2019s account without further effort. Consequently, the risk profile combines confidentiality loss of secret credentials with potential long\u2011term unauthorized access.
