Machine-written summary

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

Nginx UI versions from 1.9.10-0.20260421071512-7864e378f5cf before 1.9.10-0.20260728074146-a467ed652591 (Go module github.com/0xJacky/Nginx-UI) are affected. An authenticated user can upload a forged encrypted backup to the restore endpoint, overwrite the application config, set nginx command settings, and then run arbitrary commands in the nginx-ui runtime. Upgrade to 1.9.10-0.20260728074146-a467ed652591, which is the fixed version. The source gives no workaround.
