Attack Vectors

CVE-2026-27428 affects the WordPress plugin Eagle Booking (slug: eagle-booking) in versions up to and including 1.3.4.3. This is a Medium severity issue (CVSS 6.5, vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).

The key business-relevant point: an attacker must be logged in with at least a Subscriber role (or higher). In many organizations, that level of access can be obtained through account reuse, credential stuffing, phishing, a compromised customer account, or an internal user account that has been taken over. Because the attack is network-based and does not require user interaction, it can be executed quietly once access is obtained.

Security Weakness

The weakness is an authenticated SQL injection vulnerability caused by insufficient escaping of a user-supplied parameter and a lack of sufficient preparation in an existing database query. In practical terms, this can allow an authenticated attacker to manipulate how the site queries its database.

According to the published advisory, this weakness can be used to extract sensitive information from the WordPress database. That matters because databases often store customer details, internal operational information, and other data that supports marketing programs and business operations.

Technical or Business Impacts

The primary impact highlighted for this vulnerability is data confidentiality risk (CVSS indicates high impact to confidentiality). For marketing leadership and executives, that can translate into exposure of customer or prospect data, campaign intelligence, pricing or partner information, and other sensitive records stored in WordPress.

Even if the website itself stays online and looks normal, unauthorized data access can trigger significant downstream consequences: brand damage, customer trust erosion, incident response costs, and potential compliance obligations depending on what data is stored and which regulations apply to your organization.

Remediation note: There is no known patch available at this time per the source advisory. You may need to implement mitigations based on your risk tolerance, and it may be best to uninstall the affected plugin and replace it.
