What is CVE-2026-111384?

The Nezha dashboard file manager prior to version 2.3.15 is susceptible to a memory exhaustion vulnerability. This issue arises because the fmStream functionality fails to impose a read limit, allowing authenticated users with file manager scopes to transmit oversized binary messages to the designated WebSocket API endpoint. Such actions can instigate an out-of-memory (OOM) kill, which could subsequently terminate all monitoring agents, thereby jeopardizing system performance and stability.

Affected Version(s)

nezha 1.0.0 < 2.3.15
