Executive Summary
In June 2026, a critical path traversal vulnerability, identified as CVE-2026-48282, was discovered in Adobe ColdFusion versions 2025.9, 2023.20, and earlier. This flaw allows unauthenticated remote attackers to execute arbitrary code on affected servers without user interaction, potentially leading to full system compromise. The vulnerability arises from improper limitation of a pathname to a restricted directory, enabling attackers to access and manipulate files outside the intended directory structure. (nvd.nist.gov)
The inclusion of CVE-2026-48282 in CISA's Known Exploited Vulnerabilities Catalog underscores the urgency for organizations to address this issue promptly. Given the active exploitation in the wild, entities using vulnerable ColdFusion versions must prioritize patching to mitigate the risk of unauthorized access and potential data breaches.
