Security Impact
CVSS: 7.1
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L).
How to Fix CVE-2019-16549
To remediate this vulnerability, upgrade all affected M2release dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.jenkins-ci.plugins.m2release</groupId>
<artifactId>m2release</artifactId>
<version>0.16.2</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.jenkins-ci.plugins.m2releaseHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2019-16549, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.jenkins-ci.plugins.m2releaseAnalyze the terminal output to locate any version of M2release in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.16.2), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.plugins.m2release command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-611: Improper Restriction of XML External Entity Reference, where the product processes an xml document that can contain xml entities with uris that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. In M2release, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "Jenkins Maven Release Plug-in Plugin retrieves XML from Nexus repository manager APIs. Maven Release Plug-in Plugin 0.16.1 and earlier does not configure the XML parser to prevent XML external entity (XXE) attacks. While Jenkins users without Overall/Administer permission are not allowed to configure a custom Nexus URL, this could still be exploited via man-in-the-middle attacks, especially if it’s not an HTTPS URL.\n\nAdditionally, a connection test form validation method does not require POST requests, resulting in a cross-site request forgery vulnerability. Combined, these two vulnerabilities allow attackers to have Jenkins parse crafted XML documents that use external entities for extraction of secrets from the Jenkins controller, server-side request forgery, or denial-of-service attacks.\n\nMaven Release Plug-in Plugin 0.16.2 configures its XML parser to prevent XML external entity (XXE) attacks. It also now requires that requests to the connection test form validation method are done via POST, which protects from cross-site request forgery attacks.",
