Attack Vectors
ZIP Code Based Content Protection (slug: zip-code-based-content-protection) versions 1.0.2 and earlier contain a High-severity SQL injection vulnerability (CVE-2025-14353, CVSS 7.5). The issue is exposed through the publicly reachable “zipcode” input, meaning an attacker does not need an account to target it.
From a business-risk perspective, this is especially concerning because ZIP-code checks are commonly placed on customer-facing pages (e.g., gated content, location-restricted offers, partner portals). If the vulnerable parameter is used anywhere on your site, an attacker can probe it remotely and attempt to pull data from the underlying WordPress database without interacting with your staff.
Security Weakness
The weakness is an unauthenticated SQL injection tied to improper handling of user-supplied input. According to the advisory, the plugin does not sufficiently escape the “zipcode” parameter and does not adequately prepare the SQL query, allowing attackers to alter database queries.
In practical terms, instead of the site treating the ZIP code as simple text, an attacker can craft inputs that influence how the database responds. This can lead to database information being exposed—without needing login credentials—making the risk profile significantly higher than many typical website issues.
Technical or Business Impacts
Confidential data exposure risk: The published impact indicates attackers may be able to extract sensitive information from the database. Depending on what your WordPress database contains, that could include customer records, business contact data, internal user information, or other stored content. Even if payment data is not stored in WordPress, disclosure of customer or prospect data can still create serious legal and reputational consequences.
Compliance and reporting pressure: For organizations subject to privacy or contractual obligations, unauthorized database access can trigger breach assessment, notification workflows, and potential regulatory scrutiny. This creates time-sensitive work for Compliance, Legal, and executive leadership, as well as unplanned costs for forensics and communications.
Brand and revenue impact: Marketing and leadership teams should treat this as a trust issue. If attackers can access sensitive data, the downstream effect can include customer churn, reduced conversion rates, partner concerns, and increased scrutiny of your digital governance.
Severity and prioritization: This vulnerability is rated High with CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), reflecting that it can be exploited over the network with low complexity and no authentication, with a high confidentiality impact.
Remediation: Update ZIP Code Based Content Protection to version 1.0.3 or newer (patched). Source advisory: Wordfence vulnerability record. CVE reference: CVE-2025-14353.
