CVE-2024-39777: Mattermost allows unsolicited invites to expose access to local channels

criticalCVSS 4.0 9.3 · 3.1 8.7GHSA-q22q-2rrf-m27p

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.
