What it is
Input is written into a web page without escaping, so an attacker's script runs in the browser of anyone who views it.
How it is reached
The record does not say yet how the flaw is reached; the description below is the best guide until it is scored.
What an attacker gains
Its impact has not been scored yet. In practice, this kind of flaw lets an attacker act inside a signed-in user's browser session.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- No fixed version is listed yet. Find every place Apache Roller runs, watch the references for a fix, and plan a replacement if it is no longer supported.
Description from NVD
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.6 allows an authenticated user with the Author role on a weblog that uses a custom theme to store script that runs in the browser of anyone who opens the file's resource URL. The fix for CVE-2026-82387 serves uploaded media as a download unless it is an image, audio, video, PDF or plain text, but media files found through a custom theme were served with the type their path implies, and the upload form let the uploader choose that path. Media uploads are disabled by default. Users are recommended to upgrade to Apache Roller 6.1.7 or later, which serves these files under the same rules as other media and no longer accepts the path from the upload form.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Web front ends and single-page apps. The flaw sits between a user's browser and the web application.
- Admin consoles served to a browser. The flaw sits between a user's browser and the web application.
Trust boundaries in play
- Between a user's browser and the web application. An attacker who crosses it can act inside a signed-in user's browser session.
Questions to answer about your own systems
- Where does Apache Roller run in your systems, and at which version?
- Which of those instances are reachable by people you do not trust?
- What can it reach once compromised: which data stores, secrets and services?
