PMD Designer has Stored XSS in VBHTMLRenderer and YAHTMLRenderer via unescaped violation messages

CVE-2026-28338 / GHSA-8rr6-2qw5-pc7r

More information

Details

Summary

PMD's vbhtml and yahtml report formats insert rule violation messages into HTML output without escaping. When PMD analyzes untrusted source code containing crafted string literals, the generated HTML report contains executable JavaScript that runs when opened in a browser.

While the default html format is not affected via rule violation messages (it correctly uses StringEscapeUtils.escapeHtml4()), it has a similar problem when rendering suppressed violations. The user supplied message (the reason for the suppression) was not escaped.

Details

VBHTMLRenderer.java line 71 appends rv.getDescription() directly into HTML:

sb.append("<td><font class=body>").append(rv.getDescription()).append("</font></td>");

YAHTMLRenderer.java lines 196–203 does the same via renderViolationRow():

private String renderViolationRow(String name, String value) {
    return "<tr><td><b>" + name + "</b></td>" + "<td>" + value + "</td></tr>";
}

Called at line 172:

out.print(renderViolationRow("Description:", violation.getDescription()));

The violation message originates from AvoidDuplicateLiteralsRule.java line 91, which embeds raw string literal values via first.toPrintableString(). This calls StringUtil.escapeJava() (line 476–480), which is a Java source escaper — it passes <, >, and & through unchanged because they are printable ASCII (0x20–0x7e).

By contrast, HTMLRenderer.java line 143 properly escapes:

String d = StringEscapeUtils.escapeHtml4(rv.getDescription());

PoC

1. Create a Java file with 4+ duplicate string literals containing an HTML payload:

public class Exploit {
    String a = "<img src=x onerror=alert(document.domain)>";
    String b = "<img src=x onerror=alert(document.domain)>";
    String c = "<img src=x onerror=alert(document.domain)>";
    String d = "<img src=x onerror=alert(document.domain)>";
}

2. Run PMD with the vbhtml format:

pmd check -R category/java/errorprone.xml -f vbhtml -d Exploit.java -r report.html

3. Open report.html in a browser. A JavaScript alert executes showing document.domain.

The generated HTML contains the unescaped tag:

<td><font class=body>The String literal "<img src=x onerror=alert(document.domain)>" appears 4 times in this file</font></td>

Tested and confirmed on PMD 7.22.0-SNAPSHOT (commit bcc646c53d).

Impact

Stored cross-site scripting (XSS). Affects CI/CD pipelines that run PMD with --format vbhtml or --format yahtml on untrusted source code (e.g., pull requests from external contributors) and expose the HTML report as a build artifact. JavaScript executes in the browser context of anyone who opens the report.

Practical impact is limited because vbhtml and yahtml are legacy formats rarely used in practice. The default html format has a similar issue with user messages from suppressed violations.

Spring Framework vulnerable to a reflected file download (RFD)

CVE-2025-41234 / GHSA-6r3c-xf4w-jxjm

More information

Details

Description

In Spring Framework, versions 6.0.x as of 6.0.5, versions 6.1.x and 6.2.x, an application is vulnerable to a reflected file download (RFD) attack when it sets a “Content-Disposition” header with a non-ASCII charset, where the filename attribute is derived from user-supplied input.

Specifically, an application is vulnerable when all the following are true:

• The header is prepared with org.springframework.http.ContentDisposition.
• The filename is set via ContentDisposition.Builder#filename(String, Charset).
• The value for the filename is derived from user-supplied input.
• The application does not sanitize the user-supplied input.
• The downloaded content of the response is injected with malicious commands by the attacker (see RFD paper reference for details).

An application is not vulnerable if any of the following is true:

• The application does not set a “Content-Disposition” response header.
• The header is not prepared with org.springframework.http.ContentDisposition.
• The filename is set via one of:
  • ContentDisposition.Builder#filename(String), or
  • ContentDisposition.Builder#filename(String, ASCII)
• The filename is not derived from user-supplied input.
• The filename is derived from user-supplied input but sanitized by the application.
• The attacker cannot inject malicious content in the downloaded content of the response.

Affected Spring Products and VersionsSpring Framework

• 6.2.0 - 6.2.7
• 6.1.0 - 6.1.20
• 6.0.5 - 6.0.28
• Older, unsupported versions are not affected

Mitigation

Users of affected versions should upgrade to the corresponding fixed version.

Affected version(s)	Fix version	Availability
6.2.x	6.2.8	OSS
6.1.x	6.1.21	OSS
6.0.x	6.0.29	Commercial

No further mitigation steps are necessary.
