ColdFusion versions 2023.18, 2025.6 and earlier are affected by an Uncontrolled Resource Consumption vulnerability that could lead to application denial-of-service. A high-privileged attacker could exploit this vulnerability and exhaust system resources, reducing application speed. Exploitation of this issue does not require user interaction.
Security readout for executives and security teams
Plain-English summary
A highly privileged attacker with adjacent-network access could make affected Adobe ColdFusion applications consume excessive resources, slowing service or causing denial-of-service. The issue does not expose or alter data according to the supplied CVSS assessment. Its low severity reflects limited availability impact and substantial attacker prerequisites.
Executive priority
Treat this as routine but time-bound maintenance rather than an emergency. Confirm exposure and follow Adobe's advisory during the normal patch cycle. Accelerate remediation for business-critical ColdFusion services, weakly segmented environments, or systems with broadly assigned administrative privileges.
Technical view
CVE-2026-27307 is a CWE-400 uncontrolled resource consumption flaw affecting ColdFusion 2023.18, ColdFusion 2025.6, and earlier versions according to the description. It has CVSS 3.1 score 2.4: adjacent access, low complexity, high privileges, no user interaction, unchanged scope, and low availability impact.
Likely exposure
Exposure is most plausible where an attacker already has high privileges and can reach ColdFusion from an adjacent network. Internet accessibility alone does not match the supplied CVSS vector. The bundle's structured affected-version entries are ambiguous, so confirm precise affected and corrected versions with Adobe.
Exploitation context
No active exploitation is established by the supplied sources, and the CVE is not identified as KEV. Exploitation requires no user interaction but does require high privileges and adjacent-network access. The expected outcome is resource exhaustion, degraded application speed, or denial-of-service—not confidentiality or integrity loss.
Researcher notes
The stated impact is availability-only resource exhaustion under CWE-400. CVSS prerequisites materially constrain risk: AV:A, PR:H, UI:N, with low availability impact. The description names 2023.18 and 2025.6 and earlier, while structured affected entries appear inconsistent; do not infer exact fixed releases without consulting APSB26-38.
Mitigation direction
Review Adobe advisory APSB26-38 for the supported update or remediation applicable to each ColdFusion deployment.
Prioritize systems where privileged users can access ColdFusion across adjacent or insufficiently segmented networks.
Restrict privileged ColdFusion access to trusted administrators and necessary management networks.
Monitor application and host resource consumption for unusual sustained exhaustion.
Validation and detection
Inventory deployed ColdFusion editions and exact versions, including development, staging, and disaster-recovery systems.
Compare each version against Adobe APSB26-38 because the bundle's structured version ranges are ambiguous.
Verify privileged access paths and determine whether untrusted adjacent-network users can reach the application.
Confirm remediation through version evidence and normal resource behavior without attempting denial-of-service testing.
