Security readout for executives and security teams
Plain-English summary
This critical ColdFusion flaw may let a low-privileged, remote attacker run code with the application user’s permissions. No user interaction is required, and successful compromise could affect confidentiality, integrity, and availability beyond the vulnerable component.
Executive priority
Treat as an urgent remediation item because compromise could enable broad code execution with minimal attacker privileges. Prioritize internet-facing and business-critical ColdFusion systems, but avoid claiming compromise solely from vulnerability presence. Obtain Adobe’s version-specific guidance immediately.
Technical view
CVE-2026-48273 is a CWE-95 eval-injection vulnerability in Adobe ColdFusion 2025 and 2023. The CVSS 3.1 score is 9.9: network-accessible, low complexity, low privileges required, no user interaction, and changed scope. The supplied affected-version data is ambiguous and should be confirmed against Adobe APSB26-119.
Likely exposure
Highest concern applies to listed ColdFusion 2025 or 2023 deployments reachable by untrusted networks or low-privileged users. Actual exposure depends on the affected functionality and precise version boundaries, which are not fully established by the supplied bundle.
Exploitation context
The record describes remote, low-complexity exploitation requiring low privileges but no user interaction. It reports arbitrary code execution as the current user. The CVE is not listed as KEV in the bundle, and no supplied source confirms active exploitation or public exploit availability.
Researcher notes
The supplied record supports CWE-95, arbitrary code execution, low required privileges, no user interaction, and changed scope. It does not identify the vulnerable code path, prerequisites beyond low privileges, fixed versions, indicators of compromise, public proof-of-concept status, or observed exploitation. The normalized affected-version entries require vendor confirmation.
Mitigation direction
- Review Adobe APSB26-119 for authoritative affected versions, updates, and mitigations.
- Apply Adobe’s prescribed ColdFusion update after appropriate change testing.
- Restrict ColdFusion access to trusted networks and authorized users until remediation is verified.
- Minimize the ColdFusion service account’s privileges and accessible resources.
Validation and detection
- Inventory all ColdFusion 2025 and 2023 instances, including externally reachable and forgotten systems.
- Compare each installed update level with Adobe APSB26-119’s affected and fixed versions.
- Confirm the prescribed Adobe update is installed and survives service restart.
- Review authentication, application, and system logs for suspicious activity around ColdFusion.
- Verify network controls prevent unnecessary access to ColdFusion services.

Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')
Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
