[KEV] CVE-2026-48282 -- CVSS 0.0 Vulnerability Briefing

[KEV] CVE-2026-48282 | CVSS 0.0 (Low) | Exploit: Operational

What Is It

CVE-2026-48282 is a path traversal vulnerability in Adobe ColdFusion that can result in arbitrary code execution under the privileges of the current user.

Technical Detail

The flaw exists in Adobe ColdFusion's file handling logic, where insufficient validation of user-supplied path input allows an attacker to traverse directory boundaries and access or manipulate files outside the intended scope. By crafting a malicious request that includes path traversal sequences, an attacker can reach sensitive server-side resources and leverage them to achieve remote code execution (RCE) in the context of the ColdFusion service account. Successful exploitation could result in full compromise of the application server, including data exfiltration, webshell deployment, or lateral movement within the hosting environment.

Exploitation Status

CISA has confirmed active exploitation in the wild, with this vulnerability added to the Known Exploited Vulnerabilities (KEV) catalog on July 7, 2026. The exploit maturity is rated Operational, meaning reliable exploit code exists and is being used in real-world attacks, not merely demonstrated in controlled research settings. Organizations running exposed ColdFusion instances should treat this as an immediate threat requiring urgent action.

Who Is Targeting This

No specific threat actor attribution at this time. Neither confirmed nor reported threat actor associations have been established for this CVE in available intelligence. This assessment may change as incident data is collected and analyzed following the KEV listing.

What To Do

Apply Adobe's patch for ColdFusion immediately. Per CISA's binding operational directive (BOD 22-01), federal civilian executive branch agencies are required to remediate KEV-listed vulnerabilities by the deadline specified in the catalog entry; organizations should treat July 7, 2026 as the reference date and verify their specific remediation deadline via the CISA KEV catalog. If patching cannot be completed immediately, restrict external network access to ColdFusion administrative interfaces, enforce allowlisting on file access paths, and review ColdFusion server logs for anomalous path traversal patterns such as sequences containing "../" or URL-encoded equivalents. Monitor for unexpected file creation events, new scheduled tasks, or outbound connections originating from the ColdFusion process, as these are common post-exploitation indicators in ColdFusion-targeted campaigns.
