SQL Injection in Fullscreen Galleria WordPress Plugin

Publication date: 2026-08-16

Last updated on: 2026-08-16

Assigner: Wordfence

Description
The Fullscreen Galleria plugin for WordPress is vulnerable to generic SQL Injection via 'href' Attribute in Post Content in all versions up to, and including, 1.6.12 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

The Fullscreen Galleria WordPress plugin up to version 1.6.12 has a SQL injection flaw. It occurs because user input in the 'href' attribute of posts is not properly escaped before being used in SQL queries. Attackers with contributor access or higher can inject malicious SQL to extract sensitive database information.

Detection Guidance

Detection requires checking for suspicious SQL queries in WordPress logs or monitoring for unusual database access patterns. No specific commands are provided in the context.

Impact Analysis

If exploited, attackers could steal sensitive data from your WordPress database, such as user credentials, personal information, or other confidential content. This could lead to data breaches, unauthorized access, or further attacks on your site.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, violating GDPR (data protection) and HIPAA (health data privacy) requirements. Organizations may face fines, legal penalties, and reputational damage if sensitive data is compromised due to this flaw.

Mitigation Strategies
  • Update the Fullscreen Galleria plugin to the latest version beyond 1.6.12.
  • Review user roles with contributor-level access and above for unauthorized changes.
  • Monitor database queries for unexpected SQL injection attempts.
