It is difficult to determine how much it will cost to fix a security flaw in WordPress, as it depends on several factors, such as the severity of the flaw, the complexity of the site, and the availability of a fix. In some cases, it may be possible to fix a security flaw using a free update or by using a security plugin. In other cases, it may be necessary to hire an information security professional to help fix the problem, which could cost hundreds or thousands of dollars.
It is important to keep in mind that while it may be tempting to try to save money on your site’s security, the cost of not fixing a security flaw can be much higher. An unfixed security flaw can expose your site to attack, which can have serious consequences, such as loss of visitor confidence or loss of sensitive data. Therefore, it is important to take steps to protect your site and be willing to invest in the security of your site if necessary.
