CVE-2026-48315: ColdFusion | Improper Input Validation (CWE-20)

ColdFusion versions 2025.9, 2023.20 and earlier are affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially gaining elevated access or control over the victim's account or session. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.

Security readout for executives and security teams

Plain-English summary

Affected Adobe ColdFusion installations could allow an unauthenticated remote attacker to achieve code execution with the victim user's privileges after convincing that user to open a malicious file. Successful exploitation could compromise the user's account or session. The reported impact is critical, but the supplied sources do not establish active exploitation.

Executive priority

Treat this as an urgent remediation item because successful exploitation could compromise sensitive data and user sessions through code execution. Prioritize exposed and high-value systems, while recognizing that exploitation requires a victim action and is not confirmed active by the supplied evidence.

Technical view

CVE-2026-48315 is an improper input validation flaw affecting ColdFusion 2025.9 and 2023.20 and earlier. Adobe reports possible arbitrary code execution in the current user's context. CVSS 3.1 is 9.3: network-accessible, low complexity, no privileges required, user interaction required, changed scope, and high confidentiality and integrity impact.

Likely exposure

Organizations running ColdFusion 2025.9 or earlier, or 2023.20 or earlier, should consider those installations potentially exposed. Practical exploitation requires a victim to open a malicious file. The supplied evidence does not identify the vulnerable component, configuration dependencies, or whether internet exposure is required beyond the network attack vector.

Exploitation context

The CVE is not listed as KEV in the supplied bundle, and no cited source here confirms exploitation in the wild. Exploitation requires user interaction. The described attack involves malicious content and may lead to script injection, account or session compromise, and code execution as the current user.

Researcher notes

The supplied record combines arbitrary code execution, malicious script injection, and malicious-file interaction without identifying the affected component or execution chain. Version-range metadata appears abbreviated, so validate remediation boundaries against Adobe APSB26-68. No exploit indicators, proof of concept, or confirmed in-the-wild activity are provided.

Mitigation direction

  • Review Adobe APSB26-68 for the vendor-supported remediation and update sequence.
  • Prioritize remediation on affected internet-facing and business-critical ColdFusion systems.
  • Warn relevant users and administrators not to open untrusted files.
  • Reduce affected users' privileges until vendor remediation is completed.

Validation and detection

  • Inventory all ColdFusion deployments and record their exact product branches and versions.
  • Identify systems running ColdFusion 2025.9, 2023.20, or earlier versions.
  • Confirm each system meets the remediated version or instructions specified in Adobe APSB26-68.
  • Review logs and endpoint telemetry for unexpected execution under ColdFusion-associated user contexts.
