# Adobe Connect: stored XSS in form fields lets scripts run in victims' browsers

Link for people: https://infrastack.ai/live/CVE-2026-122102 (this .md is for agents)

Adobe Connect has a stored cross-site scripting flaw in form fields. A low-privileged attacker can plant malicious JavaScript that runs in a victim's browser when they open the affected page, potentially taking over the victim's session or account.

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

## Affected

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

## How to check

Check your installed Adobe Connect version/build. Per APSB26-191, 12.12 and earlier on Windows without the matching letter build (12.12.a, 12.11.i, 12.10.f, 12.9.a, 12.8.a) are affected. Also check if you run Connect on other platforms or hosted: the bulletin does not say.

## Fix

Install the Adobe Connect update for your branch: 12.12.a, 12.11.i, 12.10.f, 12.9.a or 12.8.a (Windows). Adobe rates it priority 2.

## From the sources

Adobe Connect is affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low-privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim's browser when they browse to the page containing the vulnerable field, potentially gaining elevated access or control over the victim's account or session. Scope is changed.
