Summary
CVE-2025-12866 is a critical-severity Weak Password Recovery Mechanism for Forgotten Password (CWE-640) vulnerability in Org (inferred from references). Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 46th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-12 (Identity Proofing) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

CVE-2025-12866 is a critical vulnerability in EIP Plus, a product developed by Hundred Plus, stemming from a weak password recovery mechanism classified under CWE-640. The flaw enables an unauthenticated remote attacker to predict or brute-force the 'forgot password' link, allowing unauthorized password resets for any user account. Assigned a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), it was published on 2025-11-10.
An unauthenticated attacker with network access can exploit this vulnerability with low complexity and no privileges required. By predicting or brute-forcing the forgot password link, the attacker gains the ability to reset passwords for arbitrary users, potentially leading to full account takeover, high confidentiality/ integrity/availability impacts, and unauthorized access to sensitive data or systems managed via EIP Plus.
Advisories from TWCERT/CC (https://www.twcert.org.tw/en/cp-139-10491-004b0-2.html, https://www.twcert.org.tw/tw/cp-132-10490-2534b-1.html) and CHT Security (https://www.chtsecurity.com/news/20848f61-9db5-44fd-8574-c9d6a54e4010) provide details on the vulnerability; security practitioners should review these for recommended patches, workarounds, or mitigation strategies specific to EIP Plus deployments.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
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.
Mitigating Controls (NIST CSF 2.0) AI
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.
Authentication policy covers strength/MFA but does not address recovery path weaknesses.
Secure SDLC reduces implementation flaws but is not specific to password-recovery design.

Secure-coding standards can prevent weak recovery implementations, yet the control is wider in scope.
