CVE-2026-87963 Details
Description
The Yo WordPress plugin from 1.1 through 1.3.1 does not sanitize or parameterize the username request parameter before using it in a SQL query, and reads it before WordPress applies its request escaping, allowing unauthenticated attackers to perform SQL injection and read arbitrary database contents including administrator password hashes.
A SQL injection vulnerability has been identified in the Yo WordPress plugin, affecting versions 1.1 to 1.3.1. The issue arises because the plugin fails to properly sanitize or parameterize the username request parameter before incorporating it into a SQL query. Additionally, it accesses the parameter before WordPress applies its request escaping. This oversight allows unauthenticated attackers to execute SQL injection attacks and access arbitrary database contents, including administrator password hashes.
