CVE-2026-25858 — Macrozheng Mall Password Reset OTP Exposure Leading to Account Takeover

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 1.1% (30-day exploitation probability)+10
  • Technical severity (critical)+10
  • CISA SSVC: exploitation "poc"+5
  • Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Macrozheng Mall).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Search available logs for exploit probes matching the vulnerability class (authentication), errors and authentication anomalies.
