CVE-2025-27911

Name of the Vulnerable Software and Affected Versions Datalust Seq versions prior to 2024.3.13545

Description An issue in Datalust Seq allows expansion of identifiers in message templates to bypass the system's "Event body limit bytes" setting. This can lead to increased resource consumption. With sufficiently large events, it can cause disk space exhaustion if saved to disk, or terminate the server process with an out-of-memory error.

Recommendations For versions prior to 2024.3.13545, update to version 2024.3.13545 or later to resolve the issue. As a temporary workaround, consider restricting the size of events to prevent excessive resource consumption.
