Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Nezha Monitoring dashboard versions from 0.0.0-20260628010923-fd31e5f1b0f8 up to, but not including, 0.0.0-20260721131105-c893aa57867d are affected. A member account with the lowest privilege level can trigger a nil pointer dereference by racing service creation and deletion on its own service, which crashes the whole dashboard process and takes it offline for all users. The source gives no confidentiality or integrity impact. Upgrade to 0.0.0-20260721131105-c893aa57867d or later, which fixes the issue.
