CVE-2026-75682 Overview
Adobe Connect contains an SQL injection vulnerability that allows a low-privileged attacker to execute arbitrary SQL commands against the application database. Successful exploitation can lead to arbitrary code execution in the context of the current user, and the scope change indicates the impact extends beyond the vulnerable component. The flaw requires no user interaction and is exploitable over the network, making it accessible to any authenticated attacker with basic access to the platform. Adobe published fixes in Security Bulletin APSB26-150.
Critical Impact
A low-privileged, network-based attacker can execute arbitrary SQL and pivot to code execution, gaining elevated access or control over victim accounts and sessions.
Affected Products

Technical Details for CVE-2026-75682
Vulnerability Analysis
The vulnerability is classified as Improper Neutralization of Special Elements used in an SQL Command [CWE-89]. Adobe Connect fails to properly sanitize attacker-controlled input before incorporating it into SQL statements executed by the backend database. An authenticated attacker with low privileges can inject arbitrary SQL clauses to read, modify, or delete data outside their authorized scope.
Because the scope is changed, exploitation impacts resources managed by components other than the vulnerable one. The advisory states successful exploitation can result in arbitrary code execution in the context of the current user, indicating the injected SQL can be leveraged beyond simple data manipulation. No user interaction is required.
Root Cause
The root cause is insufficient input validation and lack of parameterized queries in one or more Adobe Connect request handlers. User-supplied parameters are concatenated into SQL statements without proper escaping or binding, allowing SQL syntax metacharacters to alter query semantics.
Attack Vector
The attack vector is network-based and requires authentication as a low-privileged user. An attacker submits crafted HTTP requests containing malicious SQL payloads to a vulnerable endpoint. The database executes the modified query, returning data, modifying records, or invoking database features that lead to code execution in the current user context. Session hijacking and privilege escalation follow from control over authentication-related tables or objects.
See the Adobe Security Bulletin APSB26-150 for vendor technical details. No public proof-of-concept is available at time of writing.
Detection Methods for CVE-2026-75682
Indicators of Compromise
- Unexpected SQL syntax characters such as ', --, ;, UNION, or SELECT in HTTP request parameters targeting Adobe Connect endpoints.
- Database error messages returned to clients or logged during normal user activity.
- Anomalous database query volume or duration originating from the Adobe Connect application account.
- New or modified administrator accounts, session tokens, or role assignments not tied to legitimate administrative activity.
Detection Strategies
- Enable verbose query logging on the Adobe Connect database and alert on queries containing SQL injection payload patterns.
- Deploy a web application firewall in front of Adobe Connect with SQL injection rule sets tuned to the application's expected parameters.
- Correlate authentication events with subsequent database queries to identify low-privileged accounts executing high-privilege operations.
Monitoring Recommendations
- Monitor Adobe Connect application logs for repeated failed requests, malformed parameters, or 500-series errors preceding successful requests.
- Track outbound connections from the database and application servers for signs of code execution or data exfiltration.
- Baseline normal query patterns per user role and alert on deviations, particularly stored procedure calls or writes to authentication tables.
How to Mitigate CVE-2026-75682
Immediate Actions Required
- Apply the security update referenced in Adobe Security Bulletin APSB26-150 to all Adobe Connect deployments.
- Audit existing Adobe Connect user accounts and revoke unnecessary or dormant low-privileged accounts that could be used for exploitation.
- Review database and application logs for indicators of prior exploitation, focusing on the period before patching.
- Rotate credentials, session tokens, and API keys associated with Adobe Connect after patching.
Patch Information
Adobe released fixed versions of Adobe Connect as documented in Adobe Security Bulletin APSB26-150. Administrators should consult the bulletin for exact version numbers and upgrade instructions applicable to their deployment.
Workarounds
- Restrict network access to the Adobe Connect application to trusted networks or VPN users while patching is planned.
- Deploy WAF rules to block requests containing SQL injection signatures targeting Adobe Connect URIs.
- Enforce least-privilege on the database account used by Adobe Connect to limit the impact of a successful injection.
