CVE-2026-48282

This vulnerability is like a “break out of the folder” mistake. ColdFusion is supposed to only read files from a specific safe directory, but attackers may be able to trick it into going to other locations on the server. If that happens, the attacker can potentially go further than reading files and cause harmful actions on the server.

This matters if your small business uses or hosts Adobe ColdFusion (including older releases up through 2025.9 and 2023.20). The risk is higher when the ColdFusion web service is reachable from the network because attackers don’t need special privileges or user interaction to attempt the traversal.
Only treat it as a concern if ColdFusion is exposed to users or other systems that an attacker could reach over the network.

Treat this as a high-priority patching item, even though the provided sources did not identify confirmed “exploitation in the wild” for this specific CVE. The vulnerability is severe and is designed to be triggered remotely.
With no KEV entry and no public exploit code noted, this is still urgent enough to schedule immediately if your ColdFusion is internet-accessible, rather than waiting for a routine patch cycle.

1. Confirm exposure

   • Identify whether any system in your business runs Adobe ColdFusion.
   • Record the exact ColdFusion version and deployment type (public website, internal app, behind a VPN, etc.).
   • Determine whether the ColdFusion application endpoints are reachable from the internet or from untrusted networks.

2. Check version against affected range

   • This CVE is reported to affect ColdFusion version 2025.9 and 2023.20 and earlier.

3. Apply the vendor fix

   • Use Adobe’s security advisory APSB26-68 as the source of truth for the fixed build(s) and upgrade steps.
   • Upgrade to the fixed version(s) listed in APSB26-68 for CVE-2026-48282, ensuring you complete the full upgrade procedure (not just a partial component change).
   • Note any upgrade/compatibility changes described by Adobe and test in a staging environment if available.

4. If you cannot patch immediately (temporary controls)

   • Restrict network access to ColdFusion as much as possible (e.g., only allow trusted IPs, require VPN access, or limit to an internal network).
   • Add/strengthen request filtering/WAF rules that limit path traversal patterns (where your environment supports it), but treat this as a temporary compensating control—not a replacement for the vendor patch.

5. Post-upgrade validation

   • Verify the ColdFusion service is running the updated version.
   • Review logs for abnormal file access attempts, repeated 4xx/5xx errors consistent with traversal attempts, or suspicious activity around request times.

6. Ongoing monitoring

   • Watch for new Adobe advisories or follow-on CVEs referencing CVE-2026-48282.
   • Ensure your incident/ticket process can rapidly pull logs related to ColdFusion requests if activity spikes after deployment.

CISA due date: not provided in the findings (KEV is not listed).

CVE-2026-48282 is a path traversal issue (CWE-22) in Adobe ColdFusion. The reported scope shift in the provided description indicates that the impact can include arbitrary code execution in the context of the current user. No KEV listing was found, and no dated real-world exploitation claims, ransomware activity, or mass scanning reports were provided. There is no public exploit code on record in the provided findings. A patch exists via Adobe APSB26-68. EPSS was reported as a low predicted likelihood and flat trend in the provided data; however, this CVE is still treated as high risk due to its severity and remote trigger characteristics.
