CWE: CWE-89 \u2014 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
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.

Code:
    public void testEncodeEqualToWithSpecialCharacters() throws Exception {
        PropertyIsEqualTo expr = ff.equals(ff.property("testString"), ff.literal("\\'FOO"));
        String actual = filterToSql.encodeToString(expr);
        assertEquals("WHERE testString = '\\\\''FOO'", actual);
    }
