CVE-2026-25858: macrozheng mall <= 1.0.3 Unauthenticated Password Reset via OTP Disclosure

macrozheng mall version 1.0.3 and prior contains an authentication vulnerability in the mall-portal password reset workflow that allows an unauthenticated attacker to reset arbitrary user account passwords using only a victim’s telephone number. The password reset flow exposes the one-time password (OTP) directly in the API response and validates password reset requests solely by comparing the provided OTP to a value stored by telephone number, without verifying user identity or ownership of the telephone number. This enables remote account takeover of any user with a known or guessable telephone number.

Security readout for executives and security teams

Plain-English summary

CVE-2026-25858 lets a remote unauthenticated attacker take over accounts in macrozheng mall 1.0.3 and earlier if they know or can guess a user telephone number. The reset process reportedly returns the one-time password to the requester, defeating the purpose of SMS or phone-based verification.

Executive priority

Treat as urgent for any exposed macrozheng mall deployment because it can enable full account takeover without credentials. Prioritize discovery, temporary exposure reduction, and vendor remediation tracking.

Technical view

The mall-portal password reset workflow discloses the OTP in the API response and validates resets by telephone-number-stored OTP only. Sources describe no identity or telephone ownership verification before accepting the reset, mapping to CWE-640 and CVSS 4.0 score 9.3.

Likely exposure

Internet-exposed macrozheng mall deployments running version 1.0.3 or earlier are the primary concern. Exposure depends on whether the mall-portal password reset workflow is reachable and whether user telephone numbers are known, enumerable, or guessable.

Exploitation context

The provided bundle does not show KEV listing or cited evidence of active exploitation. The attack is remote, unauthenticated, low complexity, and needs no user interaction, but the bundle only supports describing the vulnerability mechanics, not real-world exploitation activity.

Researcher notes

Evidence is strongest for the flaw class and affected workflow from the CVE description and advisory references. Patch status, exploit-in-the-wild status, and complete affected-version metadata are not established in the provided bundle.

Mitigation direction

  • Inventory macrozheng mall deployments and confirm whether version 1.0.3 or earlier is present.
  • Check the GitHub issue, CVE record, and vendor guidance for fixed versions or official remediation.
  • Restrict public access to the affected password reset workflow until vendor guidance is applied.
  • Review password reset design to ensure OTPs are never returned in API responses.
  • Monitor account reset activity for unusual telephone-number-based reset patterns.

Validation and detection

  • Confirm whether mall-portal password reset endpoints are exposed to unauthenticated users.
  • In a safe test environment, verify whether reset responses disclose OTP values.
  • Check whether reset validation binds OTPs only to telephone numbers without ownership proof.
  • Review application logs for resets followed by unexpected login or profile changes.
  • Confirm remediation by ensuring OTP values are not returned to clients.
