Exploitation Conditions in CVE-2026-75682: What a Low-Privileged Account Buys an Attacker

Low-privileged accounts possess the ability to launch attacks in Adobe Connect, as demonstrated by the CVE-2026-75682 flaw. The vulnerability, classified as SQL injection with a CVSS v3 score of 9.9 (highest), allows an attacker to gain arbitrary code execution when exploiting a low-privileged account. Although the advisory groups this flaw with eight others, CVE-2026-75682 is unique in its ability to lead to code execution through an authenticated low-privileged account without user interaction.

Any account created for instructors, students, external partners, contractors, or support staff can satisfy the precondition for this vulnerability. This broad applicability raises concerns, as credential reuse and password spraying tactics frequently result in unauthorized access to low-privileged accounts. Unfortunately, the public record does not disclose the vulnerable parameter, the specific database or component, or the path from the injected query to code execution.

Consequently, assessing exploitation difficulty becomes challenging from the advisory alone. To address this, it is advisable to assume the flaw is reachable and incorporate appropriate detection measures. These measures should focus on behaviour rather than searching for a signature, such as monitoring for unexpected child processes spawned by the Connect service, outbound connections to unfamiliar destinations, database error patterns, and file system writes outside of maintenance windows.

The authoritative fix for this vulnerability is to upgrade to Adobe Connect 12.12 or the Android app 4.5. In the interim, it is recommended to restrict the service's reachability, review and disable dormant or third-party accounts with low-privileged access, and enhance logging around the Connect service to facilitate post-patch investigations.

As of the latest query, approximately 23,660 instances of Adobe Connect were identified, indicating its widespread reach.
