Adobe ColdFusion Path Traversal Vulnerability

Who is affected

How to fix it

Adobe ColdFusion is affected by a path traversal vulnerability that can lead to arbitrary code execution. Apply the Adobe APSB26-68 update, restrict administrative interfaces, and inspect ColdFusion directories for unauthorized files. Because ColdFusion servers are often internet-facing, review logs and rotate secrets if exploitation is suspected.

1. Inventory ColdFusion servers, versions, update levels, exposed applications, and administrative interfaces.
2. Apply the Adobe ColdFusion update or hotfix referenced in APSB26-68 for CVE-2026-48282.
3. Restrict ColdFusion Administrator, RDS, debugging endpoints, and management paths to trusted admin networks only.
4. Review mappings, file upload handlers, scheduled tasks, templates, web roots, and CFIDE paths for traversal exposure.
5. Inspect web logs, ColdFusion logs, application logs, and filesystem changes for suspicious path traversal or code execution.
6. Rotate administrator passwords, datasource credentials, API keys, SMTP credentials, and application secrets if compromise is suspected.
7. Clear template cache and redeploy from trusted source if unauthorized ColdFusion or Java files are discovered.

Verify the fix

• Confirm ColdFusion reports the Adobe fixed update level for CVE-2026-48282.
• Validate administrative and CFIDE paths are not exposed to untrusted networks.
• Review logs for traversal patterns, unexpected file reads, file writes, or template execution.
• Test core application, datasource, scheduled task, and upload workflows after patching.
• Run a Fixnx scan and confirm no public ColdFusion admin exposure remains.
