CISA adds Adobe ColdFusion flaw to KEV
CISA added an actively exploited Adobe ColdFusion path traversal vulnerability to its Known Exploited Vulnerabilities catalog, directing federal agencies to remediate quickly.
CISA has added CVE-2026-48282, a path traversal vulnerability in Adobe ColdFusion, to its Known Exploited Vulnerabilities (KEV) Catalog after confirming evidence of active exploitation in the wild. Path traversal flaws remain a common vector for attackers to access sensitive files or achieve remote code execution on affected systems, making them a persistent risk for organizations running exposed ColdFusion instances.
Under Binding Operational Directive (BOD 26-04), Federal Civilian Executive Branch agencies are required to prioritize remediation of vulnerabilities in the KEV Catalog, particularly those that could grant an attacker total control of a publicly exposed asset. The directive also requires agencies to check whether systems were compromised prior to patching. While BOD 26-04 legally binds only FCEB agencies, CISA recommends all organizations adopt similar risk-based patching practices for KEV-listed vulnerabilities to reduce exposure to known exploitation.

Detection guidance
ColdFusion Java Process Spawning Command Shell
Detects cmd.exe, powershell.exe, or bash spawned by the ColdFusion Java process (coldfusion.exe/java.exe), consistent with post-exploitation of a path traversal/RCE vulnerability such as CVE-2026-48282. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

Web Shell File Write by ColdFusion Process in Webroot
Detects creation of script files (jsp, cfm, cfc, jspx) by the ColdFusion process outside of expected deployment activity, indicating possible web shell drop following exploitation of a path traversal vulnerability. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

Path Traversal Sequence in Web Request to ColdFusion Endpoint
Detects HTTP requests containing directory traversal sequences (../ or encoded equivalents) targeting ColdFusion administrative or CFIDE paths, indicative of exploitation attempts against path traversal vulnerabilities like CVE-2026-48282. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.
