newbee-mall Weak Password Hashing Allows Offline Credential Recovery.

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-26219

The vulnerability involves an internal database storage practice (unsalted password hashing). While the application itself may be web-facing, the specific vulnerable mechanism requires prior compromise or leakage of the database to be exploited, rather than being directly reachable or exploitable via an internet-facing network service.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory concerns a vulnerability in newbee-mall related to how user passwords are stored. The system uses an outdated and insecure method for hashing passwords, which means if an attacker gains access to stored password data, they could potentially recover the original passwords quickly through offline attacks. This could have implications if sensitive user information is compromised.

Weak password storage exposes user credentials.
Critical security flaw could allow easy access.
Confirm relevance and exposure of this system.

Attack Path

How an attacker could exploit the issue

An attacker could gain access to user password hashes through various means, such as a database breach or leaked backups. These hashes are then subjected to offline cracking techniques due to the weak hashing algorithm used by newbee-mall. This could lead to the recovery of plaintext passwords.

Exposed password hashes required.
Weak hashing allows rapid credential recovery.
Plaintext passwords may be exposed.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could impact user authentication when password hashes are exposed. Attackers could recover plaintext credentials from compromised hash data.

User password hashes at risk.
Offline cracking of exposed hashes.
Unauthorized account access.

Operational Fix

Recommended remediation, mitigation, and detection steps

The newbee-mall application's use of unsalted MD5 hashing for password verification presents a critical risk. This weakness allows attackers to rapidly crack user credentials if they obtain password hashes from compromised databases or backups. Owners of the newbee-mall application, along with their respective infrastructure and security teams, must prioritize identifying all instances of this software, assessing their business criticality and external exposure, and planning remediation.

Application owners should address the vulnerability.
Verify password hashing implementation and exposure.
Plan and coordinate secure credential storage updates.

Frequently asked questions

What is newbee-mall?

newbee-mall is an open-source e-commerce platform designed to provide a complete shopping experience, including product browsing, shopping carts, and user account management. It serves as a practical example for developers building retail web applications, often used for learning or as a base for custom online stores.

What is the vulnerability in CVE-2026-26219?

This vulnerability is classified as Use of a Broken or Risky Cryptographic Algorithm (CWE-327). Specifically, the application relies on unsalted MD5 hashes to store user passwords. Because it lacks unique per-user salts and computational overhead, these hashes are highly susceptible to being reversed if an attacker obtains the database, making it trivial to recover actual user passwords using modern hardware.

How does an attacker trigger this bug?

The flaw is not triggered by sending malicious web requests. Instead, an attacker must first obtain the password database or a backup file containing the hashes. Once they possess this data, they perform the cracking process offline on their own systems. Simply interacting with the public-facing website does not trigger the hash recovery process.

Is my newbee-mall instance at risk?

While newbee-mall is web-based, Halo Surface Signal notes that this is primarily a database storage issue. Your risk depends on whether an unauthorized party can access your backend data, such as through a secondary database breach. While internet-facing apps are always at higher general risk, this specific vulnerability requires that the underlying credential storage be compromised first.

What should I do to secure my software?

Prioritize identifying all deployed instances of the affected software. Since this is a fundamental design flaw, you should coordinate with your development team to move away from unsalted MD5 hashing and implement modern, salted password hashing standards like Argon2 or bcrypt. Until an update is applied, ensure your database backups are encrypted and strictly access-controlled.
