What is CVE-2025-4396?

The Relevanssi – A Better Search plugin for WordPress presents a vulnerability that allows time-based SQL injection through the cats and tags query parameters. This issue affects all versions up to and including 4.24.4 for free and 2.27.4 for premium users. The vulnerability arises from inadequate data sanitation on user-supplied inputs, as well as insufficient preparation of existing SQL queries. As a result, unauthenticated attackers can manipulate SQL queries, potentially retrieving sensitive information from the database without the need for authentication.

Affected Version(s)

Relevanssi – A Better Search * <= 4.24.4

Relevanssi – A Better Search (Pro) * <= 2.27.4
