Halo Surface Signal score for CVE-2026-40329

Masa CMS is a content management system. These platforms are standard, internet-facing web applications designed to deliver content to users, making them naturally exposed to public network requests and traffic. The vulnerability exists within a component reachable via common web requests to the application.

Horizon Alert

Summary of the vulnerability and why it matters

A critical SQL injection vulnerability exists in Masa CMS, allowing unauthenticated remote attackers to execute arbitrary SQL commands. This could lead to unauthorized access, data modification, or complete system control.

  • Attackers can access sensitive data.
  • System integrity and administrative control are at risk.
  • Vulnerability is reachable from the internet.

Attack Path

How an attacker could exploit the issue

An unauthenticated remote attacker can exploit this vulnerability by sending specially crafted requests to the `beanFeed.cfc` component. By manipulating the `sortBy` parameter, the attacker can inject malicious SQL code that will be executed by the server's database. This allows them to compromise sensitive data or gain unauthorized control over the application.

  • Reachable via network.
  • Unauthenticated access required.
  • Targets SQL database.

Live Threat

Current exploitation, exposure, and threat context

The SQL injection vulnerability in Masa CMS presents a clear risk due to its unauthenticated and remote exploitability, allowing attackers to manipulate the database. While not yet listed as actively exploited or in the KEV, SQL injection vulnerabilities are a classic and persistent threat favored by attackers for data exfiltration and system compromise.

  • SQL injection is a common attack.
  • Public exploits are not yet observed.
  • Recency signals are limited.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Prioritize patching Masa CMS to versions 7.2.10, 7.3.15, 7.4.10, or 7.5.3 to address the SQL injection vulnerability. If immediate patching is not feasible, implement Web Application Firewall (WAF) rules to block suspicious SQL patterns targeting the `beanFeed.cfc` component's `sortBy` parameter to prevent exploitation.

  • Apply available version updates.
  • Deploy WAF rules for `sortBy` parameter.
  • Monitor traffic for SQL injection attempts.

Frequently asked questions

What is the nature of the vulnerability found in Masa CMS?

Masa CMS versions 7.5.2 and earlier contain a SQL injection vulnerability within the beanFeed.cfc component. This weakness allows unauthenticated remote attackers to execute arbitrary SQL commands by exploiting the getQuery function's handling of the sortBy parameter. The application fails to properly sanitize or parameterize this input, leading to potential data breaches and system compromise.

How does the SQL injection vulnerability in Masa CMS (CVE-2026-40329) work, and what is its weakness class?

The vulnerability is classified as CWE-89, SQL Injection. Attackers can exploit it by sending crafted requests to beanFeed.cfc, manipulating the sortBy parameter to inject malicious SQL. This bypasses normal security checks, allowing direct interaction with the application's database.

What is the trigger path for the Masa CMS SQL injection vulnerability, and can its scope be negated?

The vulnerability is triggered through specially crafted network requests targeting the `beanFeed.cfc` component. Specifically, manipulation of the `sortBy` parameter allows for SQL code injection. The scope is not negated as the vulnerability is exposed via the network and requires no prior authentication.

How relevant is the Masa CMS SQL injection vulnerability, considering its exposure and potential impact?

Masa CMS is a common, internet-facing web application, making this vulnerability highly relevant. The Halo Surface Signal indicates a 'Likely' risk due to the platform's inherent exposure. An unauthenticated attacker can execute arbitrary SQL commands, posing a significant threat to data integrity and confidentiality.

What practical steps should be taken to respond to the Masa CMS SQL injection vulnerability?

To mitigate this SQL injection vulnerability, it is recommended to update Masa CMS to versions 7.2.10, 7.3.15, 7.4.10, or 7.5.3. If immediate patching is not possible, configure Web Application Firewall (WAF) rules to block malicious SQL patterns in the 'sortBy' parameter sent to 'beanFeed.cfc'.
