PMD Designer's release key passphrase (GPG) available on Maven Central in cleartext

CVE-2025-23215 / GHSA-88m4-h43f-wx84

More information

Details

Summary

While rebuilding PMD Designer for Reproducible Builds and digging into issues, I found out that passphrase for gpg.keyname=0xD0BF1D737C9A1C22 is included in jar published to Maven Central.

Details

See https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/net/sourceforge/pmd/pmd-designer/README.md

Impact

After further analysis, the passphrase of the following two keys have been compromised:

1. 94A5 2756 9CAF 7A47 AFCA BDE4 86D3 7ECA 8C2E 4C5B: PMD Designer (Release Signing Key) releases@pmd-code.org
   This key has been used since 2019 with the release of net.sourceforge.pmd:pmd-ui:6.14.0.
   The following versions are signed with the same key: 6.16.0, 6.17.0, 6.19.0.
2. EBB2 41A5 45CB 17C8 7FAC B2EB D0BF 1D73 7C9A 1C22: PMD Release Signing Key releases@pmd-code.org
   This key has been used since 2020 with the release of net.sourceforge.pmd:pmd-ui:6.21.0
   and all the other modules of PMD such as net.sourceforge.pmd:pmd-core:6.21.0.
   This key has also been used for PMD 7, for the designer, e.g. net.sourceforge.pmd:pmd-designer:7.0.0
   and net.sourceforge.pmd:pmd-core:7.0.0.
   The versions between 6.21.0 and 7.9.0 are signed with this key.
   Additionally the key has been used to sign the last release of PMD Eclipse Plugin 7.9.0.v20241227-1626-r.

The keys have been used exclusively for signing artifacts that we published to Maven Central under group id net.sourceforge.pmd and once for our pmd-eclipse-plugin. The private key itself is not known to have been compromised itself, but given its passphrase is, it must also be considered potentially compromised.

As a mitigation, both compromised keys have been revoked so that no future use of the keys are possible.
For future releases of PMD, PMD Designer and PMD Eclipse Plugin we use a new release signing key:
2EFA 55D0 785C 31F9 56F2 F87E A0B5 CA1A 4E08 6838 (PMD Release Signing Key releases@pmd-code.org).

Note, that the published artifacts in Maven Central under the group id net.sourceforge.pmd are not
compromised and the signatures are valid. No other past usages of the private key is known to the project
and no future use is possible due to the revocation. If anybody finds a past abuse of the private key,
please share with us.

Note, the module net.sourceforge.pmd:pmd-ui has been renamed to net.sourceforge.pmd:pmd-designer since PMD 7, so there won't be a fixed version for pmd-ui.

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.
