Wheels Framework SQL Injection Vulnerability

Wheels versions 1.1.8 through 4.1.1 contain a SQL injection vulnerability when caller-supplied quoted values are parsed again as SQL by dynamic finders (such as findOneByEmail), the query builder's where(property, value) and where(property, operator, value), string/UUID-key lookup paths (findByKey, updateByKey, deleteByKey and findOrCreateBy...), and validatesUniquenessOf.

The parser incorrectly treats a doubled single quote as the end of a literal. Applications passing request data to these APIs can expose authentication, password-reset or token lookups, and data to unauthorized access; numeric-column values are not affected.

A similar concern affects query-builder whereBetween() in 4.0.0 through 4.1.1: string/date bounds can alter SQL on MySQL/MariaDB with backslash escaping enabled. This is fixed in 4.1.2.
