Summary

CVE-2026-48362 is a critical OS command injection vulnerability (CWE-78) in Adobe ColdFusion that allows an unauthenticated, remote attacker to achieve arbitrary code execution in the context of the current user, with no user interaction required. The vulnerability affects ColdFusion 2025 and ColdFusion 2023 and carries the maximum CVSS v3.1 base score of 10.0.

Technical details

  • Root cause: Improper neutralization of special elements used in an OS command (CWE-78), allowing attacker-supplied input to be interpreted as OS commands by the ColdFusion server.
  • Trigger conditions: No authentication or user interaction is required to exploit the flaw.
  • Attack vector: Network — exploitable remotely over the network against internet-exposed ColdFusion instances.
  • Impact: Full compromise of confidentiality, integrity, and availability (all rated High); the CVSS vector’s Scope: Changed (S:C) indicates the vulnerability can impact resources beyond the vulnerable component itself, consistent with arbitrary code execution on the underlying host.

Affected software

  • Adobe ColdFusion 2025 — versions 0 through 2025.0.11 (fixed in 2025.0.12)
  • Adobe ColdFusion 2023 — versions 0 through 2023.0.22 (fixed in 2023.0.23)

Severity

  • CVSS v3.1 Base Score: 10.0 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade Adobe ColdFusion 2025 to version 2025.0.12 or later, and Adobe ColdFusion 2023 to version 2023.0.23 or later, per Adobe’s security bulletin APSB26-90.
  • If patching cannot be performed immediately: Restrict network access to ColdFusion administrative and application endpoints, place instances behind a firewall or VPN, and monitor for anomalous process execution or outbound connections from the ColdFusion server as an interim compensating control until the patch is applied.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
