CVE-2025-22144 is a critical-severity Externally Controlled Reference to a Resource in Another Sphere (CWE-610) vulnerability in Namelessmc Nameless. Its CVSS base score is 9.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked in the top 48% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

CVE-2025-22144 is a critical vulnerability (CVSS 9.8, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) in NamelessMC, a free website software for Minecraft servers. The flaw stems from improper handling of password reset codes during user validation. Specifically, when an account is approved via email, the reset_code remains NULL, but manual validation by a user with admincp.core.emails or admincp.users.edit permissions sets the reset_code to an empty value instead of NULL. This enables unauthorized password resets. The issue is linked to CWE-610 (Externally Controlled Reference to a Resource in Another Sphere) and CWE-640 (Weak Password Recovery Mechanism for Forgotten Password).
An unauthenticated attacker can exploit this vulnerability remotely with low complexity and no user interaction by sending a request to the /forgot_password/ endpoint (e.g., http://localhost/nameless/index.php?route=/forgot_password/&c=). This allows the attacker to reset the password of any user account, resulting in full account takeover and potential compromise of associated Minecraft server access or other linked resources.
The NamelessMC GitHub security advisory (GHSA-p883-7496-x35p) and release notes for version 2.1.3 confirm the issue has been fixed in that update, urging all users to upgrade immediately. No workarounds are available.

reset code is NULL, but when the account is manually validated by a user with admincp.core.emails or admincp.users.edit permissions then the reset_code will no longer be NULL but empty. An attacker can request http://localhost/nameless/index.php?route=/forgot_password/&c= and reset the password. As a result an attacker may compromise another users password and take over their account. This issue has been addressed in release version 2.1.3 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Mitigating Controls (NIST 800-53 r5) AI
Enforces access authorizations so externally supplied references cannot reach resources outside the intended sphere.
Controls information flow between security domains, blocking resolution of external references to unintended spheres.
Identity proofing at appropriate assurance levels ensures forgotten-password recovery cannot succeed without strong verification of the user.
Authenticator management requires secure distribution, reset, and verification procedures that directly address weak password recovery flows.
Validates information inputs, directly stopping externally controlled names or references from being accepted.
Monitors and controls boundary communications, limiting the ability of external references to reach protected resources.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Credential lifecycle management directly includes password reset/recovery flows.
Identity proofing is the core control that prevents weak or bypassed recovery mechanisms.
Secure development practices directly require input validation and reference sanitization that prevent externally-controlled resource references.
Runtime monitoring of software and data flows can detect anomalous external resource accesses that result from this weakness.
Authentication policy covers strength/MFA but does not address recovery path weaknesses.
Network segmentation and access controls limit the blast radius when an external reference escapes its intended sphere.

Security testing can detect instances of the weakness but does not prevent it at design or coding time.
Strong authentication-information lifecycle rules directly address weak password-recovery flows.
Secure development lifecycle mandates validation of all external references to prevent uncontrolled resource access.
Application security requirements explicitly call for controls against externally supplied resource identifiers.
Secure architecture principles reduce the attack surface for externally controlled references but do not prescribe specific validation rules.
Secure coding standards require input validation and canonicalization to block externally controlled resource references.
