AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Network-reachable app server with low-complexity, no-interaction RCE; PR:L reflects the required low-privilege foothold, and S:C plus total impact justify C/I/A:H.

ColdFusion is affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.
AnalysisAI
Arbitrary code execution in Adobe ColdFusion 2023 and 2025 allows an attacker with low privileges to run code in the context of the current user without any user interaction, per Adobe advisory APSB26-82 (CVSS 9.9, scope-changed). The flaw stems from improper input validation (CWE-20) and carries a total technical impact per CISA SSVC. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to the ColdFusion server plus a low-privilege authenticated foothold (CVSS PR:L) - it is not fully unauthenticated - but needs no user interaction (UI:N) and low attack complexity (AC:L), and applies to default-configured Adobe ColdFusion 2023 (≤ Update 21) and ColdFusion 2025 (≤ Update 10). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed rather than uniformly alarming. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained low-privilege authenticated access to an internet-reachable ColdFusion 2023 or 2025 server submits crafted input to a vulnerable endpoint that fails proper validation, causing the server to execute attacker-supplied code with no user interaction. Because the CVSS scope is changed and technical impact is total, the attacker can leverage the resulting code execution to move beyond the vulnerable component toward the host or other applications. … |
| Remediation | Vendor-released patch: apply the fixed builds identified in Adobe security bulletin APSB26-82 - ColdFusion 2023 Update 22 and ColdFusion 2025 Update 11, which are the first patched versions above the vulnerable ranges (ColdFusion 2023 ≤ Update 21 and ColdFusion 2025 ≤ Update 10). … Detailed patch versions, workarounds, and compensating controls in full report. |
