Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-10 requires validation of all information inputs using defined mechanisms, directly mitigating the improper input validation (CWE-20) in ColdFusion that enables security feature bypass.
SI-2 mandates timely identification, reporting, and correction of system flaws, such as applying the vendor patch from Adobe APSB26-38 for this specific CVE.
AC-3 enforces approved authorizations for logical access to system resources, helping to block unauthorized access even if input validation is bypassed.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Improper input validation in public-facing Adobe ColdFusion server enables unauthenticated network attackers to bypass security controls for unauthorized access, directly matching exploitation of public-facing applications.

Deeper analysisAI
CVE-2026-27282 is an Improper Input Validation vulnerability (CWE-20) affecting Adobe ColdFusion versions 2023.18, 2025.6, and earlier. This issue enables a security feature bypass, allowing attackers to circumvent protective measures.
An unauthenticated attacker (PR:N) can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L), achieving high integrity impact (I:H) without confidentiality or availability disruption (C:N/A:N) and no scope change (S:U), per its CVSS v3.1 base score of 7.5. The vulnerability description states that exploitation requires user interaction, though the CVSS vector indicates none is needed (UI:N). Successful exploitation lets the attacker bypass security controls to gain unauthorized access.
Adobe's security bulletin APSB26-38, published April 14, 2026, provides details on the vulnerability at https://helpx.adobe.com/security/products/coldfusion/apsb26-38.html. Security practitioners should consult this advisory for recommended mitigations and patches.
