# Revive Adserver: reflected XSS in invocation-tag generator via banner identifier

Link for people: https://infrastack.ai/live/CVE-2026-108564 (this .md is for agents)

Revive Adserver's invocation-tag generation interface reflects an attacker-supplied banner identifier into HTML form fields without encoding, when Direct Selection is enabled. An attacker who gets an logged-in user to open a crafted URL can run JavaScript in that user's browser session.

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

## Affected

- vendor:Revive Adserver affected range not listed fixed no fixed version listed

## How to check

- Check the installed Revive Adserver version in the admin footer or the package files; versions `6.0.8` and earlier are affected.
- Check whether Direct Selection is enabled in the Revive Adserver settings (it is disabled by default).

## Fix

- Revive Adserver: upgrade to `6.0.9`, which HTML-encodes banner identifier values in the invocation-option form fields.

## Timeline

## From the sources

A reflected cross-site scripting vulnerability in the invocation-tag generation interface of Revive Adserver 6.0.8 and earlier allows an unauthenticated attacker to execute JavaScript in an authenticated user's browser by persuading them to visit a crafted URL. When Direct Selection is enabled, an attacker-controlled banner identifier can be included in HTML form fields without appropriate encoding. Direct Selection is disabled by default. The issue is fixed in Revive Adserver 6.0.9 by HTML-encoding banner identifier values in the invocation-option form fields.
