How to Fix CVE-2025-61788
To remediate this vulnerability, upgrade all affected Opencast common 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.opencastproject</groupId>
<artifactId>opencast-common</artifactId>
<version>Latest secure release</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.opencastprojectHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2025-61788, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.opencastprojectAnalyze the terminal output to locate any version of Opencast common in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.opencastproject 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.

"details" : "Prior to Opencast 17.8 and 18.2 the paella would include and render some user inputs (metadata like title, description, etc.) unfiltered and unmodified.\n\n### Impact\n\nThe vulnerability allows attackers to inject and malicious HTML and JavaScript in the player, which would then be executed in the browsers of users watching the prepared media. This can then be used to modify the site or to execute actions in the name of logged-in users.\n\nTo inject malicious metadata, an attacker needs write access to the system. For example, the ability to upload media and modify metadata. This cannot be exploited by unauthenticated users.\n\n### Patches\n\nThis issue is fixed in Opencast 17.8 and 18.2, however they are not published to the Maven registry.\n\n### Resources\n\n- [Patch fixing the issue](https://github.com/opencast/opencast/commit/2809520fa88d108d8104c760f00c10bad42c14f9)\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n* Open an issue in [our issue tracker](https://github.com/opencast/opencast/issues)\n* Email us at [security@opencast.org](mailto:security@opencast.org)",
