- CWE-863 - Incorrect Authorization
Summary
gomatrixserverlib is a Go library for matrix protocol federation. Dendrite is a Matrix homeserver written in Go, an alternative to Synapse. The power level parsing within gomatrixserverlib was failing to parse the `"events_default"` key of the `m.room.power_levels` event, defaulting the event default power level to zero in all cases. Power levels are the matrix terminology for user access level. In rooms where the `"events_default"` power level had been changed, this could result in events either being incorrectly authorised or rejected by Dendrite servers. gomatrixserverlib contains a fix as of commit `723fd49` and Dendrite 0.9.3 has been updated accordingly. Matrix rooms where the `"events_default"` power level has not been changed from the default of zero are not vulnerable. Users are advised to upgrade. There are no known workarounds for this issue.

Summary
Gomatrixserverlib is a Go library for matrix federation. Gomatrixserverlib is vulnerable to server-side request forgery, serving content from a private network it can access, under certain conditions. The commit `c4f1e01` fixes this issue. Users are advised to upgrade. Users unable to upgrade should use a local firewall to limit the network segments and hosts the service using gomatrixserverlib can access.
