Key points
- The National Vulnerability Database lists CVE-2026-106624 with a CVSS score of 10.0, rating it as critical.
- The flaw is classified as CWE-94, involving improper control of code generation, leading to potential code injection.
- Exploitation requires no user interaction, allowing attackers to execute arbitrary code in the context of the current user.
Adobe ColdFusion servers running specific versions face a severe security risk that allows attackers to run unauthorized code without any user interaction. This vulnerability, tracked as CVE-2026-106624, carries a maximum severity score, indicating a high likelihood of successful exploitation if the software is exposed to the internet. System administrators must verify their installations immediately to determine if their environments fall within the affected version ranges.
How it unfolded
- The National Vulnerability Database published a record for CVE-2026-106624, identifying a critical flaw in Adobe ColdFusion.
- The entry describes the issue as an improper control of code generation, commonly known as code injection.
- Analysts determined that the vulnerability allows for arbitrary code execution in the context of the current user.
- The assessment notes that exploitation does not require any form of user interaction, making it a zero-click threat.
Who is affected
Organizations using Adobe ColdFusion 2025 are at risk if they are running versions up to 2025.0.13. According to the National Vulnerability Database, all releases of the 2025 branch up to and including 2025.0.13 are vulnerable to this code injection flaw. This means that any server running these older builds is potentially exposed to remote attacks that could compromise the system.
Administrators managing Adobe ColdFusion 2023 deployments face similar exposure. The National Vulnerability Database states that versions up to 2023.0.25 are affected by this critical vulnerability. Teams supporting legacy or long-term support releases must check their patch levels carefully. If the installed version is older than the specified cutoff, the system is considered vulnerable to the described code injection attack vector.
What happens next
The National Vulnerability Database record indicates that the scope of the vulnerability is changed. This classification is noted in the source material alongside the critical severity rating. Because the flaw allows for arbitrary code execution, the potential impact includes data theft or system disruption. No details on active exploitation in the wild were provided in the source material.
Adobe has not released a public statement detailing a patch or mitigation strategy in the provided source material. Consequently, system administrators should assume that no fix has been confirmed yet unless they have received direct communication from the vendor. The absence of a confirmed patch means that immediate protective measures, such as network segmentation or access restrictions, may be necessary to reduce the risk of exploitation while awaiting an official update.
The background in plain language
Code injection occurs when an application incorrectly processes untrusted data, treating it as executable code instead of plain text. This allows attackers to insert malicious commands that the server runs directly. Remote code execution means an attacker can run these commands from a different computer, often without needing to log in first. Zero-click vulnerabilities are particularly dangerous because they do not require a user to click a link or open a file, making them harder to detect and prevent through user training alone.
Background: Remote code execution vulnerabilities
Monitor for unexpected child processes, sudden spikes in outbound network traffic, and anomalous file creation. Combine static analysis with runtime behavior monitoring to catch execution attempts before they establish persistence or exfiltrate data.

What to do and how to stay safe: Adobe ColdFusion
- Audit your ColdFusion installations to identify if you are running versions 2025.0.13 or older, or 2023.0.25 or older.
- Restrict network access to ColdFusion servers to only trusted IP addresses until a patch is available.
- Monitor server logs for unusual activity or unexpected code execution attempts that could indicate exploitation.
- Contact your vendor support channel to inquire about the availability of an emergency patch or temporary mitigation.
