Reference: CVE-2026-48282
1. What is being reported?
Adobe ColdFusion versions 2025.9, 2023.20 and earlier have a weakness called a 'path traversal' vulnerability. This means attackers can access restricted parts of the system and run malicious code as if they were the user running ColdFusion. The problem can be exploited remotely and does not require any user action.
2. What this means in plain English
If your organisation uses Adobe ColdFusion, hackers could break into your system and take control, potentially stealing data or causing damage. Because the attack does not need anyone to open a link or file, it can happen silently and quickly.
3. Could this affect a small business?
Small businesses or charities using Adobe ColdFusion versions 2025.9, 2023.20 or earlier could be at risk. If you do not use ColdFusion, this vulnerability does not affect you.
4. What to do now
- Check if your organisation uses Adobe ColdFusion and identify the version.
- Contact your IT provider or software supplier to confirm if you are affected.
- Apply any security updates or mitigations recommended by Adobe immediately.
- If updates are not available, consider discontinuing use of ColdFusion or isolating it from internet access until fixed.
5. Ask your IT provider
Can you confirm if our Adobe ColdFusion installation is affected by CVE-2026-48282 and what steps are being taken to protect us?
6. Bottom line
If you use Adobe ColdFusion, act now to update or secure it to prevent hackers from taking control of your systems.
