CVE-2026-48324: Adobe ColdFusion RCE Vulnerability

CVE-2026-48324 Overview

CVE-2026-48324 is a SQL injection vulnerability in Adobe ColdFusion caused by improper neutralization of special elements used in SQL commands [CWE-89]. Successful exploitation allows an attacker to execute arbitrary code in the context of the current user. The flaw is network-exploitable, requires no user interaction, and results in a scope change that impacts resources beyond the vulnerable component. Adobe published advisory APSB26-82 identifying affected ColdFusion 2023 and ColdFusion 2025 releases.

Critical Impact
Attackers with low-privileged network access can inject SQL statements that lead to arbitrary code execution and full compromise of confidentiality, integrity, and availability on affected ColdFusion servers.

Affected Products

Adobe ColdFusion 2023 (base release through Update 21)
Adobe ColdFusion 2025 (base release through Update 10)
Systems running vulnerable ColdFusion instances exposed to untrusted network input

Technical Details for CVE-2026-48324

Vulnerability Analysis

CVE-2026-48324 stems from ColdFusion's failure to properly neutralize special elements passed into SQL commands. An authenticated attacker with low privileges can craft input that alters the structure of backend SQL queries. Because ColdFusion executes query results within the application context, the injection path chains into arbitrary code execution on the host.

The vulnerability carries a changed scope, meaning exploitation impacts components beyond the vulnerable ColdFusion process. This typically indicates the injected payload can escape the database interaction boundary and influence the underlying operating system or adjacent services. High impact ratings for confidentiality, integrity, and availability reflect complete server compromise potential.

No public proof-of-concept or in-the-wild exploitation has been reported at the time of publication. However, ColdFusion has a history of being targeted by opportunistic scanning and mass exploitation once technical details become available.

Root Cause

The root cause is insufficient input validation and unsafe query construction within ColdFusion's database interaction layer. Special SQL metacharacters supplied through application inputs reach the query executor without proper parameterization or escaping. This weakness is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

Attack Vector

Exploitation occurs remotely over the network against ColdFusion endpoints that accept attacker-controlled input reaching a vulnerable database interaction. The attacker requires low-level privileges on the ColdFusion instance but no user interaction. Once the injected SQL is processed, the payload leverages ColdFusion's execution context to run arbitrary code with the privileges of the ColdFusion service account. Refer to the Adobe ColdFusion Security Advisory APSB26-82 for vendor-specific technical guidance.

Detection Methods for CVE-2026-48324

Indicators of Compromise

Unexpected outbound connections originating from the ColdFusion service account or jrun.exe/coldfusion.exe processes
New or modified .cfm, .cfc, or .jsp files in web-accessible directories that were not deployed by administrators
Anomalous child processes spawned by ColdFusion (for example cmd.exe, powershell.exe, /bin/sh) executing reconnaissance or download commands
Database logs showing malformed queries, stacked statements, or use of xp_cmdshell, LOAD_FILE, or INTO OUTFILE

Detection Strategies

Enable and centrally collect ColdFusion application logs, web server access logs, and database audit logs for correlation
Baseline expected query patterns and alert on injected SQL syntax such as UNION SELECT, tautologies, or comment sequences appearing in request parameters
Monitor for process lineage anomalies where the ColdFusion JVM spawns interactive shells or scripting engines
Deploy web application firewall (WAF) rules aligned with OWASP CRS SQL injection signatures in blocking mode

Monitoring Recommendations

Inventory all ColdFusion 2023 and 2025 instances, including internal and internet-facing deployments, and track their update level
Alert on new administrative accounts created within ColdFusion Administrator or the backend database
Continuously monitor /CFIDE/ and /cfusion/ URI paths for scanning behavior and abnormal POST payload sizes

How to Mitigate CVE-2026-48324

Immediate Actions Required

Apply the Adobe security updates referenced in advisory APSB26-82 to all ColdFusion 2023 and 2025 installations without delay
Restrict network access to ColdFusion Administrator and internal service endpoints to trusted management networks only
Rotate credentials for the ColdFusion service account and any database accounts reachable from the ColdFusion instance
Review web-root directories for unauthorized files and audit ColdFusion scheduled tasks for suspicious entries

Patch Information

Adobe has released fixes for CVE-2026-48324 in the versions listed in Adobe Security Bulletin APSB26-82. Administrators should upgrade to the latest available update for both ColdFusion 2023 and ColdFusion 2025 branches. Verify successful installation by checking the update level in ColdFusion Administrator after applying the patch.

Workarounds

Enforce parameterized queries in custom .cfm/.cfc code using cfqueryparam for every user-supplied value
Run the ColdFusion service under a least-privileged account and restrict its database user to the minimum required permissions
Place ColdFusion behind a reverse proxy or WAF configured to inspect and block SQL injection payloads
Disable unused ColdFusion features and remove sample applications from production servers

bash

# Example: enforce parameterized queries in ColdFusion templates
# Replace unsafe concatenation:
#   <cfquery name="q" datasource="ds">SELECT * FROM users WHERE id = #url.id#</cfquery>
# With parameterized input:
<cfquery name="q" datasource="ds">
    SELECT * FROM users
    WHERE id = <cfqueryparam value="#url.id#" cfsqltype="cf_sql_integer">
</cfquery>
