{"id":"CVE-2023-28107","state":"PUBLISHED","title":"Discourse vulnerable to multisite DoS by spamming backups","description":"Discourse is an open-source discussion platform. Prior to version 3.0.2 of the `stable` branch and version 3.1.0.beta3 of the `beta` and `tests-passed` branches, a user logged as an administrator can request backups multiple times, which will eat up all the connections to the DB. If this is done on a site using multisite, then it can affect the whole cluster. The vulnerability is patched in version 3.0.2 of the `stable` branch and version 3.1.0.beta3 of the `beta` and `tests-passed` branches. There are no known workarounds.","publishedAt":"2023-03-17T16:23:31.324Z","updatedAt":"2025-02-25T14:54:15.962Z","severity":{"score":4.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["discourse discourse"],"affected":[{"vendor":"discourse","product":"discourse","versions":[{"version":"stable < 3.0.2","status":"affected"},{"version":"beta < 3.1.0.beta3","status":"affected"},{"version":"tests-passed < 3.1.0.beta3","status":"affected"}]}],"references":["https://github.com/discourse/discourse/security/advisories/GHSA-cp7c-fm4c-6xxx","https://github.com/discourse/discourse/pull/20700","https://github.com/discourse/discourse/pull/20701","https://github.com/discourse/discourse/commit/0bd64788d2b4680c04fbef76314a24884d65fed9","https://github.com/discourse/discourse/commit/78a3efa7104eed6dd3ed7a06a71e2705337d9e61"],"weaknesses":["CWE-770"],"ingestedAt":"2026-10-29T20:05:52.290Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/28xxx/CVE-2023-28107.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-28107","state":"PUBLISHED","datePublished":"2023-03-17T16:23:31.324Z","dateUpdated":"2025-02-25T14:54:15.962Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-03-10T18:34:29.227Z"},"containers":{"cna":{"title":"Discourse vulnerable to multisite DoS by spamming backups","descriptions":[{"lang":"en","value":"Discourse is an open-source discussion platform.
