Network-reachable, unauthenticated, no-interaction authorization bypass with a scope change justifies AV:N/AC:L/PR:N/UI:N/S:C and C:H/I:H; availability set A:L since the description cites only read/write, not disruption.

DescriptionNVD

ColdFusion is affected by an Incorrect Authorization vulnerability that could result in privilege escalation. An attacker could leverage this vulnerability to gain unauthorized read and write access. Exploitation of this issue does not require user interaction. Scope is changed.

AnalysisAI

Privilege escalation in Adobe ColdFusion 2023 (through Update 21) and ColdFusion 2025 (through Update 10) allows a remote, unauthenticated attacker to bypass authorization checks and gain unauthorized read and write access. Because the CVSS vector marks scope as changed (S:C) with PR:N and no user interaction, the attacker can act beyond the ColdFusion application boundary, yielding the maximum CVSS base score of 10.0. …

Vulnerability AssessmentAI

Exploitation No special conditions - remote unauthenticated exploitation (AV:N/AC:L/PR:N/UI:N) against network-reachable Adobe ColdFusion 2023 (≤Update 21) and ColdFusion 2025 (≤Update 10) instances, with no user interaction required. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals are notably split. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who can reach a ColdFusion server over the network sends a crafted request to an endpoint whose authorization check is faulty, causing the server to grant privileged access without valid credentials. With the resulting unauthorized read and write access and the changed scope, the attacker reads sensitive data and modifies server-side resources, potentially pivoting to broader compromise. …
Remediation Vendor-released patch: upgrade Adobe ColdFusion 2023 to Update 22 and Adobe ColdFusion 2025 to Update 11 as specified in Adobe advisory APSB26-82 (https://helpx.adobe.com/security/products/coldfusion/apsb26-82.html), prioritizing any ColdFusion server reachable from untrusted networks. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all Adobe ColdFusion 2023 and 2025 instances across your environment, identify exposed systems, and immediately restrict network access to ColdFusion administrative ports (default 8500, 8501) using firewall rules and network segmentation. …
