Explain it like I’m five

From one network hop away, an attacker can be treated as authorized for functions that end in code execution.

SIMPLIFIED_ATTACK_PATH03 STEPS
  1. 01Reach ColdFusion

    An attacker sends requests to a ColdFusion server.

  2. 02Flaw engaged

    The vulnerable function processes the attacker's input without the control it needed.

  3. 03Code executes

    Arbitrary code runs in the context of the ColdFusion service user.

What happened

Adobe disclosed CVE-2026-75994 in bulletin APSB26-144: an incorrect authorization vulnerability (CWE-863) in ColdFusion that could result in arbitrary code execution; Adobe’s vector is adjacent-network rather than fully remote.

Adobe lists the affected ColdFusion releases in APSB26-144 (the NVD record names the 2023 update line through 2023.0.25, with 2023.0.26 listed as unaffected). Apply the update Adobe provides for your release line.

What to do

  1. Inventory every ColdFusion deployment, including test, training, and individually managed instances.
  2. Apply the vendor fix or upgrade exactly as directed in the linked vendor bulletin or advisory.
  3. Restrict network access to ColdFusion while remediation is underway, especially for internet-facing instances.
  4. Review application and server logs for requests to ColdFusion from peer systems that do not normally administer it, and actions with no matching login.
  5. Check for accounts, content, or configuration created outside normal change processes, and rotate exposed credentials where access cannot be ruled out.
  6. Verify the deployed version or patch level after remediation.

Management note

Adjacent-network reach still puts every flat internal network in scope. Update and segment application servers while you are at it.
