**Name of the Vulnerable Software and Affected Versions** Quassel version 0.10.0 **Description** The issue allows remote attackers to cause a denial of service, resulting in an application crash. This can be achieved by sending the "/op *" command in a query. **Recommendations** For Quassel version 0.10.0, consider restricting access to the CoreUserInputHandler::doMode function until a patch is available. As a temporary workaround, avoid using the "/op *" command in queries to minimize the risk of exploitation.
