CVE-2025-23026

CVE-2025-23026: jte's HTML templates containing Javascript template strings are subject to XSS

Summary

Jte HTML templates with script tags or script attributes that include a Javascript template string (backticks) are subject to XSS.

Details

The javaScriptBlock and javaScriptAttribute methods in the Escape class (source) do not escape backticks, which are used for Javascript template strings. Dollar signs in template strings should also be escaped as well to prevent undesired interpolation.

PoC

Use the Jte Gradle Plugin with the following code in src/jte/xss.jte:

@param String someMessage
<!DOCTYPE html>
<html lang="en">
<head>
    <title>XSS Test</title>
    <script>window.someVariable = `${someMessage}`;</script>
</head>
<body>
<h1>XSS Test</h1>
</body>
</html>

Use the following Java code to demonstrate the XSS vulnerability:

final StringOutput output = new StringOutput();
JtexssGenerated.render(new OwaspHtmlTemplateOutput(output), null, "` + alert(`xss`) + `");
renderHtml(output);

Impact

HTML templates rendered by Jte's OwaspHtmlTemplateOutput in versions less than or equal to 3.1.15 with script tags or script attributes that contain Javascript template strings (backticks) are vulnerable.

Root Cause Analysis

The vulnerability stems from two methods in the Escape class handling JavaScript contexts. The commit diff shows these functions lacked escaping for backticks (used in JS template literals) and dollar signs (used in template interpolation). This matches the CWE-79/CWE-150 descriptions and the PoC demonstrating XSS via unescaped template strings. The high confidence comes from direct references in vulnerability details, commit patches adding specific escaping logic, and test cases validating these fixes.
