Reference: CVE-2025-62593
1. What is being reported?
The Ray AI software, used by developers for computing tasks, has a serious security weakness. It relies on a weak method to check web browsers, which attackers can bypass using a special technique involving malicious websites. This allows attackers to run harmful commands on the developer’s machine without permission. The problem affects versions before 2.52.0 and has been fixed in that version.
2. What this means in plain English
If your organisation uses Ray software for AI development, an attacker could exploit this flaw to take control of a developer’s computer by tricking them into visiting a harmful website or seeing a malicious advertisement. This could lead to data theft, disruption, or further attacks on your systems.
3. Could this affect a small business?
Small businesses or charities that do not use Ray software or do not have developers working with it are unlikely to be affected. However, if your organisation uses Ray for AI development or computing tasks, you should take this seriously and act quickly.
4. What to do now
- Check if your organisation uses Ray software and identify the version installed.
- If Ray is used, ensure it is updated to version 2.52.0 or later immediately.
- Avoid visiting unknown or untrusted websites, especially on machines running Ray.
- Ask your IT provider to confirm that all mitigations and patches recommended by the vendor and security authorities are applied.
5. Ask your IT provider
Can you confirm whether we use Ray AI software, and if so, have we updated it to version 2.52.0 or later to fix the critical security vulnerability CVE-2025-62593?
6. Bottom line
If you use Ray AI software, update it now to prevent attackers from exploiting a critical security flaw.
