Discourse is an open source discussion platform. Prior to version 3.0.6 of the stable
branch and version 3.1.0.beta7 of the beta
and tests-passed
branches, a malicious user can prevent the defer queue from proceeding promptly on sites hosted in the same multisite installation. The issue is patched in version 3.0.6 of the stable
branch and version 3.1.0.beta7 of the beta
and tests-passed
branches. There are no known workarounds for this vulnerability. Users of multisite configurations should upgrade.
