ColdFusion - Path Traversal (CVE-2026-48282)

CVE-2026-48282 is a critical path traversal vulnerability in Adobe ColdFusion versions 2025.9, 2023.20, and earlier, allowing remote attackers to execute arbitrary code without any user interaction. This flaw enables threat actors to access restricted directories and potentially take full control of affected systems, posing a severe risk to data confidentiality, integrity, and availability.

CrowdSec has been tracking this vulnerability and its exploits since 15th of July 2026.

CrowdSec network observations suggest that most exploitation of CVE-2026-48282 involves focused reconnaissance to identify viable targets. Attackers typically tailor their campaigns based on system exposure and configuration. It is unlikely that a given attack is accidental. CrowdSec network telemetry also shows that exploitation of CVE-2026-48282 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit the RDS interface by sending POST requests to /CFIDE/main/ide.cfm?ACTION=FILEIO to write arbitrary files, often targeting web-accessible directories for remote code execution. Subsequent GET requests to /CFIDE/<filename>.txt are used to verify successful file upload.
