CVE-2026-82009: Adobe Campaign Classic SQL Injection Flaw

CVE-2026-82009 Overview

CVE-2026-82009 is a SQL injection vulnerability in Adobe Campaign Classic (ACC) tracked under [CWE-89]. An attacker with high privileges can inject arbitrary SQL commands through improperly neutralized special elements. Successful exploitation leads to arbitrary code execution in the context of the current user. The flaw is network-exploitable, requires no user interaction, and changes scope, meaning impact extends beyond the vulnerable component.

Critical Impact
Authenticated attackers can execute arbitrary SQL commands and achieve code execution on Adobe Campaign Classic deployments, compromising confidentiality, integrity, and availability across affected systems.

Affected Products

Adobe Campaign Classic (versions up to and including 7.4.4 build 9401)
Adobe Campaign Classic deployments on Linux
Adobe Campaign Classic deployments on Microsoft Windows

Technical Details for CVE-2026-82009

Vulnerability Analysis

Adobe Campaign Classic fails to properly neutralize special elements passed to SQL commands. An authenticated attacker with high privileges submits crafted input that the application concatenates directly into database queries. The database then executes the attacker-controlled SQL. Because the CVSS scope is changed, the compromise extends beyond the vulnerable component into adjacent systems.

The flaw enables arbitrary code execution in the context of the current user. Attackers can read or modify marketing data, exfiltrate customer records, tamper with campaign workflows, and pivot into downstream systems reachable from the Campaign server. See the Adobe Security Advisory APSB26-142 for vendor guidance.

Root Cause

The root cause is improper neutralization of special elements used in SQL commands [CWE-89]. Adobe Campaign Classic constructs SQL statements without adequately sanitizing or parameterizing input received from privileged users. Attacker-supplied metacharacters escape the intended query context and alter statement semantics.

Attack Vector

The attack vector is network-based and requires authenticated access with high privileges. No user interaction is required. An attacker who already holds a privileged Campaign account, or who compromises one through credential theft or session abuse, sends malicious payloads to a vulnerable endpoint. The injected SQL executes with the privileges of the Campaign database user, enabling command execution and lateral impact.

No verified proof-of-concept exploit code is publicly available for CVE-2026-82009 at the time of publication. Refer to the vendor advisory for technical details.

Detection Methods for CVE-2026-82009

Indicators of Compromise

Unusual SQL error messages in Adobe Campaign Classic application logs, particularly syntax errors involving quotes, semicolons, or comment sequences (--, /*).
Unexpected database queries originating from Campaign service accounts that reference system tables, xp_cmdshell, or COPY ... FROM PROGRAM constructs.
Outbound network connections from the Campaign application host to unfamiliar external endpoints following privileged user activity.
New or modified operator accounts, workflows, or JavaScript activities created outside of change-control windows.

Detection Strategies

Enable verbose SQL query logging on the Campaign database and alert on statements containing stacked queries, UNION SELECT patterns, or database-specific command execution primitives.
Correlate authentication events for high-privilege Campaign operators with subsequent anomalous query volume or query complexity.
Deploy web application firewall (WAF) rules that inspect requests to Campaign SOAP and HTTP endpoints for SQL metacharacters in parameter values.

Monitoring Recommendations

Baseline normal query patterns for Campaign service accounts and alert on deviations in table access, query length, or execution time.
Monitor for process creation events on the Campaign server that spawn shells (cmd.exe, powershell.exe, /bin/sh) as a child of the database or application service.
Forward Campaign application, IIS or Apache, and database audit logs to a centralized SIEM with retention sufficient for incident investigation.

How to Mitigate CVE-2026-82009

Immediate Actions Required

Apply the security update referenced in Adobe Security Advisory APSB26-142 to all Adobe Campaign Classic instances.
Inventory all Campaign Classic deployments, including staging and disaster-recovery environments, and confirm version 7.4.4 build 9401 or earlier is not exposed.
Rotate credentials for all high-privilege Campaign operators and the database service account used by Campaign.
Review Campaign audit logs for suspicious privileged activity dating back to the earliest logs available.

Patch Information

Adobe published the fix in security bulletin APSB26-142. Administrators should install the vendor-supplied update on all Campaign Classic instances as soon as possible. Consult Adobe Security Advisory APSB26-142 for the specific fixed build numbers and upgrade procedures for both Linux and Windows deployments.

Workarounds

Restrict network access to the Campaign Classic administrative and SOAP endpoints to trusted management networks only.
Enforce the principle of least privilege by reducing the number of accounts granted high-privilege Campaign roles.
Require multi-factor authentication for all Campaign operator accounts to reduce the risk of credential-based access.
Deploy a WAF in front of Campaign endpoints with signatures tuned to block SQL injection payloads until patching completes.
