Commentary: A weakness in the software behind your website can become a threat to your revenue, customers and business reputation.

The recent report by Press KL on October 22, 2026, about critical vulnerabilities in PHP highlights an important issue for business owners: a problem with website software can quickly become a business problem.

For many companies, a website is more than an online presence. It generates sales, attracts customers, processes enquiries, supports payments and stores business information. If the technology behind it is vulnerable, the consequences can extend far beyond the IT department.

The key question every business owner should ask is simple: If my website were compromised or forced offline tomorrow, how much would it cost my business?

What is PHP, and why should business owners care?

PHP is a programming language used to build and operate websites and web applications. It helps websites process information, connect to databases and perform functions such as handling customer enquiries, managing accounts and supporting online transactions.

Think of your website as your digital shopfront. Customers see the products and services displayed on the screen, but behind the scenes, software keeps everything running. PHP may be part of that system.

A website can look professional and operate normally while still relying on outdated or vulnerable software.

PHP is widely used across the internet, making its security relevant to businesses in many industries. However, not every website using PHP is affected by the vulnerabilities reported. The actual risk depends on the software version, configuration and security measures in place.

For business owners, the lesson is clear: A website that looks secure is not necessarily a website that is secure.

Five ways a website vulnerability can hurt your business

1. Lost sales and revenue

If your business depends on online orders, bookings, customer enquiries or digital services, website downtime can mean lost income. Customers who cannot complete a transaction may turn to competitors instead.

Even if the website is restored within hours, the business may still lose sales and valuable opportunities.

2. Customer information at risk

A security vulnerability could allow attackers to access systems or information without permission, depending on the weakness and existing safeguards.

If customer or business data is exposed, you may face investigation costs, regulatory obligations and the difficult task of explaining the incident to affected customers.

3. Unexpected recovery costs

Recovering from a cyber incident may require technical specialists, system restoration, forensic investigations, legal advice and additional security measures.

For small and medium-sized businesses, these unexpected expenses can place considerable pressure on cash flow.

4. Damage to your reputation

Customers trust businesses to protect their information and deliver reliable services. A serious security incident can weaken that trust and make customers think twice before returning.

For a small business that depends on repeat customers and word-of-mouth referrals, reputational damage can be particularly difficult to overcome.

5. Disruption beyond the website

Your website may be connected to customer databases, internal systems, business applications or administrative accounts. If those connections are not adequately protected, a website compromise could create wider operational risks.

The impact depends on how your systems are designed and secured, but business owners should never assume that a website problem will remain confined to the website.

AI is making the cybersecurity challenge more urgent

Artificial intelligence is changing how quickly software weaknesses can be identified and analysed. AI-assisted tools can help security researchers find vulnerabilities, but similar capabilities may also be misused by cybercriminals.

This creates a challenge for businesses that rely on outdated software or slow security processes.

A vulnerability that becomes publicly known may attract attention from attackers before a business has completed its usual IT reviews or arranged a maintenance window.

Business owners should therefore avoid assuming that their company is too small to attract cybercriminals or that an obscure website will escape attention.

Cybersecurity is no longer just about preventing attacks. It is about being able to respond quickly when weaknesses are discovered.

What should business owners do?

You do not need to become a cybersecurity expert, but you do need to know whether your business is protected.

Here are six practical steps to take.

• Know what powers your website. Ask your website developer, hosting provider or IT team whether your website uses PHP and which version is running.
• Check for vulnerabilities. Ask your technical provider to assess whether your systems are affected by the reported security issues and to follow official guidance on applying fixes or other protective measures.
• Keep software updated. Ensure your website platform, plugins, applications and server software receive appropriate security updates. Avoid leaving outdated components unattended.
• Protect your backups. Maintain secure backups and periodically test whether your website and business data can be restored successfully.
• Have a recovery plan. Decide how you would continue accepting orders, communicating with customers and delivering essential services if your website became unavailable.
• Hold your service providers accountable. If an external company manages your website, ask who is responsible for security updates, monitoring, incident reporting and recovery. Request confirmation when important fixes have been completed.

These actions are relevant to businesses of all sizes. You may not control every technical detail, but you can ensure that someone qualified is responsible for managing the risks.

Five questions to ask your website developer

Business owners can start with five straightforward questions:

1. Does my website use PHP, and is the version still supported?
2. Have you checked whether my website is affected by the recently reported vulnerabilities?
3. How quickly can security updates be applied when a serious vulnerability is discovered?
4. If my website is hacked or goes offline, how quickly can it be restored?
5. What customer information could be exposed if my website were compromised?

A reliable developer or IT provider should be able to explain the answers in plain language rather than relying on technical jargon.

Protecting your business starts before an attack

The PHP vulnerability issue is a reminder that digital business comes with responsibilities. A website may be one of your most valuable business assets, but it can also become a source of financial loss if it is not properly maintained.

This does not mean every website using PHP is vulnerable or that every business needs to shut down its online services. The right response is to establish whether your systems are affected and take appropriate action based on verified technical advice.

Ultimately, business owners should treat cybersecurity as part of everyday business management, alongside cash flow, customer service and operational planning.

You do not need to understand every line of code. You do need to know who is protecting your systems, whether your software is maintained and what happens if something goes wrong.

Your website is not just a digital shopfront. It is part of your business infrastructure. Protecting it means protecting your income, your customers and the future of your business.
