1 technique across 1 tactic: Privilege Escalation

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Requires an existing low-privileged authenticated account on an affected Adobe ColdFusion instance (2023 up to and including 2023.0.25, or 2025 up to and including 2025.0.13); no user interaction is needed (UI:N). The incorrect authorization check (CWE-863) allows that account to escalate into arbitrary code execution in the current user context, with a changed scope extending impact beyond the vulnerable component. Limiting factors: the attacker must already authenticate at a low privilege level (PR:L), and the provided CVSS vector lists AV:L (local), which - if accurate - would constrain exploitation to local/console-adjacent access rather than fully remote; this limiting factor conflicts with the RCE/Authentication Bypass tags and should be confirmed with Adobe.

Impact

This is a high-severity, high-priority flaw that warrants prompt patching but carries notable signal conflicts. The CVSS 3.1 base score of 8.8 (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) reflects an easy-to-exploit, low-privilege path to arbitrary code execution with full confidentiality, integrity and availability impact and a scope change, meaning compromise extends beyond the vulnerable component. However, the vector specifies AV:L (local attack vector), which conflicts with the input Tags 'Authentication Bypass' and 'RCE' that imply a remotely reachable, pre-/low-auth bypass - this discrepancy should be verified against Adobe advisory APSB26-144, as ColdFusion incorrect-authorization RCE issues have historically been network-reachable (AV:N). No EPSS score, no CISA KEV listing, and no public POC are present in the provided data, so there is no evidence of active exploitation or weaponization yet. That said, Adobe ColdFusion has a strong history of post-disclosure exploitation and multiple past KEV entries, so despite the currently low exploitation signals this should be treated as a real priority rather than a high-CVSS-but-low-real-risk issue, especially for internet-exposed instances. Authentication requirement: PR:L in the CVSS vector indicates an authenticated (low-privileged) attacker.

Exploit ScenarioDerived

A low-privileged authenticated user of an affected ColdFusion server (2023 ≤2023.0.25 or 2025 ≤2025.0.13) abuses an incorrect authorization check to perform actions beyond their permission level, culminating in arbitrary code execution in the context of the current user without any user interaction. Because scope is changed, the resulting code execution can affect resources beyond the vulnerable module. No public exploit code is identified at time of analysis.

AnalysisAIv1 – Oct 13, 2026

Authenticated low-privileged users on Adobe ColdFusion 2023 through 2023.0.25 and ColdFusion 2025 through 2025.0.13 can exploit an incorrect authorization weakness (CWE-863) to execute arbitrary code in the context of the current user, with changed scope extending impact beyond the vulnerable component. The assessed CVSS 3.1 vector is AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H (8.8), so an existing low-privileged account is required and no user interaction is needed; the AV:L value suggests local/console-adjacent access even though the supplied tags include Authentication Bypass and RCE. No public exploit was identified at time of analysis; this is a high-severity, high-priority flaw warranting prompt patching, but the attack-vector and tag conflict should be confirmed with Adobe.

RemediationAI

Patch available per vendor advisory: Adobe APSB26-144; exact fixed version not provided in the supplied data. Apply the fixed ColdFusion update referenced in that advisory for the affected 2023 and 2025 release trains, because the affected version ceilings are 2023.0.25 and 2025.0.13 and fixes are expected in later updates. If immediate patching is not possible, reduce exposure by restricting local and console access to ColdFusion hosts, limiting or disabling unnecessary low-privileged ColdFusion accounts, reviewing authorization role mappings, and monitoring for unexpected child processes or code execution from the ColdFusion service; these compensating controls may break legitimate delegated workflows and do not eliminate the authorization flaw. No public exploit was identified at time of analysis, but the high severity and RCE potential justify prioritizing remediation.

Technical ContextAI · show details

CWE-863 (Incorrect Authorization) means ColdFusion does not properly enforce access controls on a resource or function, allowing a low-privileged authenticated user to perform actions that should require higher privileges. In this case, the incorrect authorization check can lead to arbitrary code execution under the current user, and S:C indicates the impact crosses a security boundary beyond the vulnerable component. Affected releases are Adobe ColdFusion 2023 up to and including 2023.0.25 and ColdFusion 2025 up to and including 2025.0.13, per EUVD/ENISA; no CPE strings were provided. The CVSS vector AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H is internally notable because AV:L suggests local/console-adjacent exploitation while the supplied tags include Authentication Bypass and RCE, so the attack vector should be validated against Adobe advisory APSB26-144.

DescriptionCVE.org

ColdFusion is affected by an Incorrect Authorization vulnerability that could result in arbitrary code execution in the context of the current user. A low-privileged attacker could exploit this vulnerability to execute arbitrary code. Exploitation of this issue does not require user interaction. Scope is changed.

Executive ViewAI

Why It Matters

Adobe ColdFusion 2023 (through 2023.0.25) and ColdFusion 2025 (through 2025.0.13) contain an incorrect authorization flaw that allows an already authenticated low-privileged user with local/console-adjacent access to execute arbitrary code in the current user's context, potentially exposing or altering sensitive data and disrupting ColdFusion-hosted services. Because exploitation requires an existing low-privileged account and no public exploit has been identified at time of analysis, the immediate risk is concentrated among organizations that expose local access or have weak account controls, but the high confidentiality, integrity, and availability impact makes this a priority for security leadership. No vendor-released patch is identified at time of analysis, so leadership should direct interim access controls and monitoring while awaiting a fix.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Restrict local/console-adjacent access to trusted administrators, enforce least privilege and MFA for ColdFusion accounts, disable or remove unused low-privileged accounts, isolate affected instances, and monitor for unexpected code execution.
