CVE-2026-105140

Estado: AplazadaBaja (2.3)—

Obot 0.25.0 anterior a 0.25.6 y 0.26.0 anterior a 0.26.1 contiene una condición de carrera en las actualizaciones de grupos del proveedor de autenticación que puede restaurar pertenencias a grupos recién revocadas en el proveedor de identidad. Cuando actualizaciones superpuestas para el mismo usuario se confirman fuera de orden, se persisten pertenencias obsoletas y el usuario conserva el acceso basado en grupos revocado durante unos diez minutos.
