WebVella ERP through 1.8.8 SQL Injection via EQL Query API

WebVella ERP through 1.8.8 contains an sql injection vulnerability that allows any authenticated user to inject SQL through WHERE-clause text literals in the EQL query API. Attackers can send crafted single-quoted literals to POST /api/v3/en_US/eql, escaping the unsanitized EqlBuilder SQL interpolation to read unauthorized entities, including user and role tables.
