# Adobe Connect: SQL injection lets a low-privileged user run code

Link for people: https://infrastack.ai/live/CVE-2026-121908 (this .md is for agents)

Adobe Connect has an SQL injection flaw in which special characters are not neutralized before being used in a database query. A low-privileged attacker could exploit it to execute arbitrary code in the context of the current user, without user interaction.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Adobe Connect affected <= 12.12 (Windows) fixed 12.12.a, 12.11.i, 12.10.f, 12.9.a, 12.8.a

## How to check

Check your Adobe Connect on-prem version (Windows): 12.12 or earlier without the matching patch letter (12.12.a, 12.11.i, 12.10.f, 12.9.a, 12.8.a) is affected.

## Fix

Install the Adobe Connect patch for your branch: 12.12.a, 12.11.i, 12.10.f, 12.9.a or 12.8.a (Windows), per APSB26-191.

## Documents

- [advisory] APSB26-191 Security update available for Adobe Connect https://www.adobe.com/trust/security/products/connect/apsb26-191.html

## From the sources

Adobe Connect is affected by an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability that could result in arbitrary code execution in the context of the current user. A low-privileged attacker could exploit this vulnerability to execute arbitrary code. Exploitation of this issue does not require user interaction. Scope is changed.
