The Matrix specification specifies a list of [event authorization rules](https://spec.matrix.org/v1.2/rooms/v9/#authorization-rules) which must be checked when determining if an event should be accepted into a room. In versions of Synapse up to and including version 1.61.0, some of these rules are not correctly applied. An attacker could craft events which would be accepted by Synapse but not a spec-conformant server, potentially causing divergence in the room state between servers. Administrators of homeservers with federation enabled are advised to upgrade to version 1.62.0 or higher. Federation can be disabled by setting [`federation_domain_whitelist`](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#federation_domain_whitelist) to an empty list (`[]`) as a workaround.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2022-31152","url":"https://www.suse.com/security/cve/CVE-2022-31152"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1203105 for CVE-2022-31152","url":"https://bugzilla.suse.com/1203105"}],"title":"SUSE CVE CVE-2022-31152","tracking":{"current_release_date":"2025-02-16T07:26:02Z","generator":{"date":"2023-02-15T03:25:44Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2022-31152","initial_release_date":"2023-02-15T03:25:44Z","revision_history":[{"date":"2023-02-15T03:25:44Z","number":"2","summary":"Current version"},{"date":"2025-01-01T03:03:33Z","number":"3","summary":"Current version"},{"date":"2025-02-14T07:42:59Z","number":"4","summary":"Current version"},{"date":"2025-02-16T07:26:02Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
