CVE-2026-47928 is an Improper Input Validation vulnerability in Adobe ColdFusion that affects versions 2023.19, 2025.8, and earlier. The flaw allows remote attackers to execute arbitrary code with no user interaction required. The scope of the vulnerability is changed, indicating that the impact extends beyond the vulnerable component. The CVSS v3.1 vector indicates the attack requires adjacent network access (AV:A), has low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and results in high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No vendor patch or official remediation is currently documented.

Successful exploitation can lead to arbitrary code execution in the context of the current user, potentially allowing full compromise of the affected system's confidentiality, integrity, and availability. The vulnerability does not require user interaction and can be exploited remotely from an adjacent network. This poses a critical risk to systems running affected versions of Adobe ColdFusion.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, organizations should monitor Adobe's security advisories for updates. Implement network-level controls to restrict access to ColdFusion services from untrusted sources where possible.
