      "value": "BigBlueButton is an open-source virtual classroom designed to help teachers teach and learners learn. An attacker with a valid join link to a meeting can trick BigBlueButton into generating a signed join link with additional parameters. One of those parameters may be \"role=moderator\", allowing an attacker to join a meeting as moderator using a join link that was originally created for viewer access. This vulnerability has been patched in version(s) 2.6.18, 2.7.8 and 3.0.0-alpha.7."

Un atacante con un enlace de entrada v\u00e1lido para una reuni\u00f3n puede enga\u00f1ar a BigBlueButton para que genere un enlace de entrada firmado con par\u00e1metros adicionales.
