Machine-written summary

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

Nginx UI (github.com/0xJacky/Nginx-UI) is vulnerable through the Casdoor SSO login flow, where the OAuth state parameter is a fixed value rather than a per-login random value, and the callback does not check it. An attacker who gets a victim's browser to submit the attacker's own authorization code can log the victim in as the attacker, so the victim's later configuration changes are visible to the attacker. Upgrade to 1.9.10-0.20260703131214-23d1934099b0 or later. Until patched, disable Casdoor SSO.
