# Adobe Connect: incorrect authorization lets attackers escalate privileges

Link for people: https://infrastack.ai/live/CVE-2026-121352 (this .md is for agents)

Adobe Connect has an Incorrect Authorization flaw (CWE-863) that a network attacker with no login and no user interaction can use to escalate privileges and reach sensitive resources (CVSS 10.0, scope changed). Adobe patched it on Nov 10 2026 in APSB26-191 and says it knows of no exploitation.

_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 server version (Windows). If it is 12.12 or earlier and lacks the patch build for your branch (12.12.a, 12.11.i, 12.10.f, 12.9.a, 12.8.a), you are exposed. Adobe's bulletin lists Windows only; also check any other deployment you run.

## Fix

Install the Adobe Connect patch for your branch (Windows): 12.12.a, 12.11.i, 12.10.f, 12.9.a or 12.8.a (APSB26-191, priority 2).
