Machine-written summary

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

Nginx UI (github.com/0xJacky/Nginx-UI) versions before 1.9.10-0.20260715121709-f92218e01054 are affected. An authenticated user who can create or modify an auto-backup task can set a name containing path traversal sequences, which lets backup archives, and for encrypted configuration backups the key file, be written outside the configured storage directory with the Nginx UI process privileges. Upgrade to 1.9.10-0.20260715121709-f92218e01054, which is the fixed version listed. The source gives no workaround.
