CVE-2024-39777

Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5 and 9.8.x <= 9.8.1 fail to disallow unsolicited invites to expose access to local channels, when shared channels are enabled, which allows a malicious remote to send an invite with the ID of an existing local channel, and that local channel will then become shared without the consent of the local admin.

Summary		(es) Las versiones de Mattermost 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5 y 9.8.x <= 9.8.1 no permiten invitaciones no solicitadas para exponer el acceso a canales locales, cuando los canales compartidos están habilitados, lo que permite que un control remoto malicioso envíe una invitación con el ID de un canal local existente, y ese canal local se compartirá sin el consentimiento del administrador local.
