{"id":"ALPINE-CVE-2024-52815","details":"Synapse is an open-source Matrix homeserver. Synapse versions before 1.120.1 fail to properly validate invites received over federation. This vulnerability allows a malicious server to send a specially crafted invite that disrupts the invited user's /sync functionality. Synapse 1.120.1 rejects such invalid invites received over federation and restores the ability to sync for affected users.","modified":"2026-11-03T06:32:50.340980374Z","published":"2024-12-03T17:15:12.267Z","upstream":["CVE-2024-52815"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2024-52815"}],"affected":[{"package":{"name":"synapse","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/synapse?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.120.1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-52815.json"}},{"package":{"name":"synapse","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/synapse?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.120.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-52815.json"}},{"package":{"name":"synapse","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/synapse?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.120.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-52815.json"}},{"package":{"name":"synapse","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/synapse?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.120.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-52815.json"}},{"package":{"name":"synapse","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/synapse?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.120.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-52815.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
