CVE-2024-52797Network attack vector

Denial of service via unbounded query retries

Published Nov 21, 2024 · Updated Oct 28, 2025

Denial of service in affected Opencast versions allows remote authenticated users to exhaust disk space via crafted search queries. The external API passes reserved Elasticsearch characters from the q parameter into query syntax, while exception handling retries the same invalid request without stopping at maxRetryAttempts. Default access requires ROLE_ADMIN or ROLE_API_SERIES_VIEW; repeated errors flood logs until disk exhaustion interrupts the service.
