How to Fix CVE-2021-26077
To remediate this vulnerability, upgrade all affected Spring Framework 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>com.atlassian.connect</groupId>
<artifactId>atlassian-connect-spring-boot</artifactId>
<version>2.1.3</version>
</dependency><dependency>
<groupId>com.atlassian.connect</groupId>
<artifactId>atlassian-connect-spring-boot</artifactId>
<version>2.1.5</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=com.atlassian.connectHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2021-26077, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=com.atlassian.connectAnalyze the terminal output to locate any version of Spring Framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.3), your application is affected.
Note: The mvn dependency:tree -Dincludes=com.atlassian.connect 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Spring Framework, 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.

Atlassian Connect Spring Boot versions 1.1.0 before 2.1.3 and versions 2.1.4 before 2.1.5 erroneously accept context JWTs in lifecycle endpoints (such as installation) where only server-to-server JWTs should be accepted, permitting an attacker to send authenticated re-installation events to an app.",
