Descriptions

The timing of a button click causing a popup to disappear was approximately the same length as the anti-clickjacking delay on permission prompts. It was possible to use this fact to surprise users by luring them to click where the permission grant button would be about to appear. This vulnerability affects Firefox ESR < 115.6 and Firefox < 121.

El timing en el que se hace clic en un botón que provoca la desaparición de una ventana emergente era aproximadamente de la misma duración que el retraso anti-clickjacking en las solicitudes de permiso. Era posible utilizar este hecho para sorprender a los usuarios atrayéndolos a hacer clic en el lugar donde el botón de concesión de permiso estaría a punto de aparecer. Esta vulnerabilidad afecta a Firefox ESR <115.6 y Firefox <121.
