{"id":"BIT-discourse-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":["CVE-2023-28107","GHSA-cp7c-fm4c-6xxx"],"modified":"2026-09-08T08:46:07.816621555Z","published":"2024-03-06T10:58:39.576Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:discourse:discourse:*:*:*:*:stable:*:*:*","cpe:2.3:a:discourse:discourse:*:*:*:*:*:*:*:*","cpe:2.3:a:discourse:discourse:*:*:*:*:beta:*:*:*","cpe:2.3:a:discourse:discourse:3.1.0:beta1:*:*:beta:*:*:*","cpe:2.3:a:discourse:discourse:3.1.0:beta2:*:*:beta:*:*:*"]},"references":[{"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"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-cp7c-fm4c-6xxx"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28107"}],"affected":[{"package":{"name":"discourse","ecosystem":"Bitnami","purl":"pkg:bitnami/discourse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.1.0"}]},{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"3.0.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/discourse/BIT-discourse-2023-28107.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
