Security alerts: 3 questions to ask your IT team

A security flaw can expose information or take a service offline. But a general alert doesn't prove your company was hit. The first step is to ask whoever takes care of the systems whether the company uses the service mentioned and whether it needs to act.

On October 21, 2026, Node.js announced fixes for four serious flaws. It is a technology that helps websites and apps run. On the same day, PHP, another technology used in websites, announced fixes for two critical flaws. In certain situations, they could let an outsider take control of the computer that keeps the site running, even without logging in. The team in charge should check whether it uses an affected version and install the indicated fix.

LiteLLM is a tool that connects artificial intelligence services to other systems. The project warned that one specific version, 1.107.0, was altered to include a malicious program. The alert applies to whoever installed and used that version in the period indicated by the project.

Railway hosts systems over the internet. On October 21, it reported that unauthorized people may have accessed information that customers stored to connect their systems, such as passwords and special access codes. In some cases, they were able to read this data. As a precaution, Railway recommended that all customers change the access information stored on the platform and check who accessed the systems. That doesn't mean every account was breached.

Three questions to pass on

You don't need to understand programming or hunt for versions on your own. Pass these questions on to the person or company that takes care of the systems:

1. Does our website or app use any of the Node.js or PHP versions mentioned in the alerts? If so, has the fix been installed?
2. Did we install and use LiteLLM 1.107.0 in the indicated period? If so, have the passwords and access codes that this tool could use been changed?
3. Do we store passwords or access codes on Railway? If so, did the team change the information stored there and check the access, as the company recommended?

Also ask for the name of whoever will check each answer and when that check will be done. There's no need to change the whole team's personal passwords without a reason related to these alerts.

The LiteLLM case also shows how important it is to know which AI tools are connected to the company's systems and what data they can access. Checking versions and fixing systems should be done by the technology team or the vendor in charge.
