CVE-2026-25858 is an authentication vulnerability (CWE-640) in macrozheng mall version 1.0.3 and prior, specifically within the mall-portal password reset workflow. The flaw stems from the password reset process exposing the one-time password (OTP) directly in the API response and validating reset requests only by comparing the provided OTP against a value stored by telephone number, without any verification of user identity or telephone number ownership. This enables unauthenticated attackers to reset arbitrary user passwords using just a victim's telephone number, which may be known or guessable. The vulnerability carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
An unauthenticated attacker with network access can exploit this vulnerability remotely and with low complexity. By obtaining a victim's telephone number, the attacker triggers the password reset flow to retrieve the OTP from the API response, then submits it along with a new password to complete the reset. This results in full account takeover, granting high-impact access to the victim's confidentiality and integrity, such as reading sensitive data or modifying account settings.
Mitigation details are available in related advisories, including the GitHub issue tracker at https://github.com/macrozheng/mall/issues/946, the project website at https://www.macrozheng.com/, and the VulnCheck advisory at https://www.vulncheck.com/advisories/macrozheng-mall-unauthenticated-password-reset-via-otp-disclosure.

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Strong authentication-information lifecycle rules directly address weak password-recovery flows.
Secure-SDLC practices can embed strong recovery design, yet the control is broader than this single weakness.
Application-security requirements can mandate secure recovery flows, but the control covers many other requirements.
Secure-coding standards can prevent weak recovery implementations, yet the control is wider in scope.
Secure-authentication requirements include robust forgotten-password procedures.
Proper access-rights provisioning can limit who can trigger recovery, but does not fix the recovery mechanism itself.
