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

Link for people: https://infrastack.ai/live/CVE-2026-121892 (this .md is for agents)

Adobe Connect has a code injection flaw that lets an attacker run arbitrary code in the context of the current user. A low-privileged attacker can trigger it without any user interaction, and the scope is changed.

_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

Self-hosted Adobe Connect on Windows: check your installed version. Adobe lists 12.12 and earlier as affected; you are fixed only on the updated build for your branch (12.12.a, 12.11.i, 12.10.f, 12.9.a, 12.8.a). Also check if you run Connect on other platforms; Adobe's bulletin lists Windows only.

## Fix

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

## 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 Control of Generation of Code ('Code 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.
