Descriptions
When downloading an update for an addon, the downloaded addon update's version was not verified to match the version selected from the manifest. If the manifest had been tampered with on the server, an attacker could trick the browser into downgrading the addon to a prior version. This vulnerability affects Firefox < 102.
Al descargar una actualización para un complemento, no se verificó que la versión de la actualización del complemento descargada coincidiera con la versión seleccionada en el manifiesto. Si el manifiesto hubiera sido manipulado en el servidor, un atacante podría engañar al navegador para que degradara el complemento a una versión anterior. Esta vulnerabilidad afecta a Firefox < 102.
