Vulnerability details
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to allocation of resources without limits or throttling in Opencast's Elasticsearch integration when processing search queries. A remote user can send a search query that generates a syntactically invalid Elasticsearch query to cause a denial of service.
The issue can trigger repeated immediate retries in an infinite loop, causing excessive log growth that may exhaust disk space. By default, the affected endpoints require ROLE_ADMIN or ROLE_API_SERIES_VIEW.
