{"id":"CVE-2023-28107","summary":"Discourse vulnerable to multisite DoS by spamming backups","details":"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.","aliases":["BIT-discourse-2023-28107","GHSA-cp7c-fm4c-6xxx"],"modified":"2026-05-15T04:06:39.392383908Z","published":"2023-03-17T16:23:31.324Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28107.json","cwe_ids":["CWE-770"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28107.json"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-cp7c-fm4c-6xxx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28107"},{"type":"FIX","url":"https://github.com/discourse/discourse/commit/0bd64788d2b4680c04fbef76314a24884d65fed9"},{"type":"FIX","url":"https://github.com/discourse/discourse/commit/78a3efa7104eed6dd3ed7a06a71e2705337d9e61"},{"type":"FIX","url":"https://github.com/discourse/discourse/pull/20700"},{"type":"FIX","url":"https://github.com/discourse/discourse/pull/20701"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:N/A:H"}]}
