- CVE-2022-36009, GHSA-grvv-h2f9-7v9c
- Affects: github.com/matrix-org/gomatrixserverlib
- Published: Aug 22, 2022
- Modified: Jun 12, 2023
Power level parsing does not parse the "events_default" key of the m.room.power_levels event, setting the event default power level to zero in all cases. This can cause events to be improperly accepted or rejected in rooms where the event_default power level has been changed.
