CVE-2023-45129 is fixed in matrix-synapse on 1 platform by DEBIAN-CVE-2023-45129 (version 1.94.0-1), released October 10, 2023. It is not reported as exploited. Patch Radar priority: Routine.
Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. Prior to version 1.94.0, a malicious server ACL event can impact performance temporarily or permanently leading to a persistent denial of service. Homeservers running on a closed federation (which presumably do not need to use server ACLs) are not affected. Server administrators are advised to upgrade to Synapse 1.94.0 or later. As a workaround, rooms with malicious server ACL events can be purged and blocked using the admin API.
