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 1.9.10-0.20260703131214-23d1934099b0 are affected. When an administrator disables an account and revokes its tokens, standalone short tokens can remain in cache, so if the account is re-enabled before the cache entry expires, a previously revoked short token authenticates again. The source describes this as a local test rather than a broader assessment, and the attacker's required access is not stated in detail beyond holding a stolen short token. Upgrade to 1.9.10-0.20260703131214-23d1934099b0 or later.
