How to Fix CVE-2023-26477
To remediate this vulnerability, upgrade all affected Xwiki platform flamingo theme ui 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.xwiki.platform</groupId>
<artifactId>xwiki-platform-flamingo-theme-ui</artifactId>
<version>13.10.10</version>
</dependency>
<dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-flamingo-theme-ui</artifactId>
<version>14.4.6</version>
</dependency>
<dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-flamingo-theme-ui</artifactId>
<version>14.9-rc-1</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.xwiki.platform
How to Check if You Are Affected
To determine whether your Java application is affected by CVE-2023-26477, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.xwiki.platform
Analyze the terminal output to locate any version of Xwiki platform flamingo theme ui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.10.10), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.xwiki.platform 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-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Xwiki platform flamingo theme ui, software state validation or input boundaries are circumvented during processing.
